let's go over the parts of the transfer
[2]
case this is actually the key to these
[4]
transfer case swaps and then when she's
[6]
broken loose just take it nice and chewy
[10]
chimp itself right out alright this is
[12]
where the magic happens when you pull
[14]
this out than maybe some gunk on it God
[15]
heard our plan and swiftly chuckled and
[18]
threw us a curve ball
[19]
what's up buck double Dean in the garage
[21]
obviously today talking about transfer
[23]
cases I am in the process of doing a
[26]
transfer case swap on my 2001 jeep grand
[28]
cherokee wmj some of you know project
[31]
Dan gave me this 242 I'm gonna use some
[33]
of the parts from this 249 that Eric and
[35]
I pulled at the junkyard we're gonna put
[38]
them together make a hybrid case that'll
[39]
work in my Jeep in the process what I
[41]
want to do is go over every aspect of a
[44]
transfer case swap there's a ton of
[46]
information out there on the internet
[47]
about it but there's two issues a lot of
[49]
it's incorrect a lot of it is uncertain
[51]
and almost all of it is incomplete so if
[53]
you're trying to research how to do a
[55]
transfer case swap you're likely running
[57]
around like a chicken with your head cut
[58]
off trying this site has information on
[60]
driveshafts this side has information on
[62]
compatibility broth let's go through
[65]
every single aspect of a transfer case
[68]
swap down to yolks and drive shafts
[71]
spline counts input shafts compatibility
[74]
everything I don't usually do this but
[76]
in the description I'm definitely going
[78]
to put timestamps because this is gonna
[80]
be a long video so if all you're looking
[82]
for is X go down in the description down
[86]
there in a squawk box and you'll be able
[88]
to find you know minute 5 skip there if
[90]
you need driveshafts minute whatever
[92]
because uh I'm gonna indulge my
[95]
enjoyment of talking on this one and
[98]
we're gonna just try to get all the
[99]
information out there so that further
[101]
ado let's dig into this alright to start
[104]
with specify this information is going
[106]
to be applicable for a lot of transfer
[108]
cases out there in the world but most
[109]
specifically it's for the new process
[111]
new venture transfer cases that are used
[113]
by Jeep Dodge Chrysler and even GM they
[117]
used this style transfer case not always
[119]
the exact same casing that the internals
[121]
often are compatible is actually a
[123]
really good video buy bleep and Jeep
[125]
where they take a 2 3 1 Jeep transfer
[129]
case and they put the internals in the
[131]
in the shell of a 2 3 3 as
[133]
ten case so that the s10 can use it and
[136]
it works fine it's great so this is
[138]
applicable for a wide range vehicles and
[141]
the interesting thing about the new
[143]
process new venture cases is that the
[146]
cases are almost identical these are two
[148]
different transfer cases right here is a
[149]
two four seven it's an all time
[152]
four-wheel-drive meaning there's no
[153]
two-wheel drive option on this it's kind
[155]
of in and all-wheel drive all the time
[157]
the viscous coupler this is out of a
[160]
2004 Jeep Grand Cherokee and if you look
[164]
at it you can notice that it's really
[166]
very similar to this two for two
[171]
that is out of a mm I believe XJ and
[176]
it's the same if I had a 95 XJ or TJ or
[179]
whatever you're gonna see the actual
[180]
shape of the case where the bolt holes
[182]
are are all very similar and it is for
[186]
that reason that it's so easy to do
[188]
swaps on Jeep Dodge Chrysler GM products
[191]
let's go over the parts of the transfer
[194]
case real quick just absolute down to
[196]
basics so you're looking at the front of
[198]
the transfer case here this is where it
[200]
mounts to the transmission on almost all
[203]
certainly all modern Jeep Dodge Chrysler
[206]
trucks and SUVs this mounting pattern is
[209]
the same so you can take a transfer case
[211]
out of a Dodge pickup truck and make it
[213]
work in a jeep or make it work in you
[216]
know vice verse or whatever so the first
[219]
thing you have is your input shaft right
[220]
here this is where the power comes from
[222]
the transmission this is actually the
[224]
key to these transfer case swaps now
[227]
these shafts all transfer cases have
[229]
them obviously but they can be different
[231]
in three ways the diameter the length or
[236]
the internal spline count now on these
[238]
two the XJ 242 and the W J 247 the
[242]
spline count is the same they both have
[244]
23 spline inside diameters they are also
[250]
the same diameter usually if the
[252]
internal spline is the same the
[253]
diameters the same the spline usually
[255]
dictates that the diameter the
[257]
difference obviously is the length that
[261]
they stick out if I were to try to put
[263]
this transfer case on this Jeep
[266]
would make contact and probably damage
[267]
the transmission conversely if I try to
[270]
throw this one right in my Jeep this is
[271]
not going to be long enough to engage
[273]
the output shaft of my transmission
[275]
enough so to make these two cases
[278]
compatible in opposite vehicles the most
[281]
basic way you take them apart and you
[284]
swap out these output input shafts now
[288]
this is possible because as they're the
[290]
same diameter the input bearing is the
[292]
same size and inside the planetary
[294]
gearset is going to be the same
[296]
the only time you can't do this quick
[298]
hot swap is if the diameter is different
[301]
meaning the input bearing is different
[303]
now you're still not sunk because a lot
[305]
of times you can just swap over this
[306]
plate which holds the input bearing
[308]
that's what makes these cases so
[310]
customizable and so swappable between
[313]
vehicles one of the reasons that I love
[315]
Jeep and dodge products is you can
[317]
really find a transfer case for your
[319]
needs and with a little bit of work and
[322]
time on the internet you can figure out
[323]
how to make it work
[324]
alright staying on the front of the case
[325]
without the input shaft we've got where
[327]
it mounts to the transmission you have
[329]
your linkage selector over here it's
[331]
going to be different depending on what
[332]
vehicle you're on on the 2 4 7 it comes
[334]
out the top and it's real tall on the XJ
[336]
2 4 2 it goes to the bottom and it's a
[338]
little shorter but it's always gonna be
[340]
right here most of the time when you do
[342]
a swap you want to keep your vehicle's
[344]
original arm so this arm is gonna end up
[347]
on this - 4 - I think right next to it
[350]
you have the front output shaft alright
[352]
this is what goes to your front drive
[353]
shaft now this is a u-joint style
[357]
yoke meaning there's a new joint
[360]
obviously at the end of that drive shaft
[363]
but a lot of these have a cup style
[367]
receiver on the front it looks like this
[369]
and what it holds is it's called a resi
[371]
pad joint
[372]
and it's basically a CV joint it's
[375]
basically a flat CV joint and they used
[379]
them in a lot of the entry-level light
[381]
duty so of Jeeps
[383]
so if you got a 4 litre Laredo Grand
[387]
Cherokee you probably had a receive a
[389]
front end as you can see it fits right
[391]
on and it looks the same at the end of
[394]
the day it's just the style of joint now
[396]
most people prefer the u-joint style
[398]
there's
[399]
they're easier to replace and they're
[401]
cheaper to replace and when these things
[403]
go bad they make a racket I had one I
[405]
bought a WJ real cheap because the
[407]
previous owners thought the transmission
[409]
was going it was just the receiver joint
[411]
that fits in here so if you have the
[413]
opportunity a junkyard swap get a
[416]
different transfer case get a different
[418]
output shaft yoke and you can switch
[421]
from a receiver to a new joint it's just
[424]
another thing to keep in mind you may
[427]
have to swap that over you may not so
[429]
confirm what output shaft you have in
[431]
the front and confirm what output joint
[434]
the donor transfer case has now if you
[437]
have to pull one of these the best way
[438]
to do it is on the vehicle you lock the
[440]
transfer case in for low and then you're
[443]
able to break free
[444]
this nut now the nut on almost all of
[447]
these all the ones I've ever encountered
[449]
is one and 1/8 inches or 28 millimeter
[452]
will work all right now here's the thing
[454]
if your goof like me and you forget to
[457]
do a while it's on the vehicle you have
[459]
a bit of a problem especially if you
[461]
have the receiver style because you
[462]
can't wedge it can't wedge anything
[464]
against it so bleep in Jeep actually
[468]
makes this it works like this so let's
[471]
say you get like project and brought me
[473]
this transfer case I had no opportunity
[474]
to pull the yoke when it was on the
[476]
vehicle so I took it off with this yoke
[479]
tool that bleep and Jeep actually sells
[481]
I bought it from him
[482]
years ago they sold on their website I
[485]
would highly recommend it mm-hmm
[486]
whatever sins Matt may be guilty of
[489]
committing against rare xjz batman
[492]
designs a tool for Jeeps
[493]
go ahead and buy that tool it's probably
[495]
dead useful a man's a genius all right
[499]
so you bolt it to your yoke I like so
[502]
then you have a few options you can get
[504]
either get a pipe on here or I like to
[508]
just put a breaker bar in the little
[511]
breaker bar half-inch breaker bar hole
[512]
up there you'll notice mine is in crazy
[514]
tight that one's the right sized bolts
[515]
doesn't matter I've got an inch and a
[519]
quarter or inch and an eighth right here
[521]
then you slip down in there now these
[524]
things are gonna be tighter than it
[527]
Turtles backside so you can try
[531]
but if you got this thing moving now
[533]
would be a really good time for an
[534]
impact gun because an impact gun will
[535]
pull that right off or a buddy to hold
[537]
you I don't have either so what I do use
[544]
the mechanics most ancient friend big
[546]
chunks of pipe get some leverage on it
[548]
now usually I do this on the shop floor
[550]
or not not on a table but this is for
[556]
science for you people so try to juggle
[558]
it easy peasy right just like that and
[576]
then when she's broken loose uh you can
[580]
just work it all right most of the time
[583]
these just slide right off but they are
[586]
RTV Don there's our TV right here so
[589]
sometimes you have to persuade them just
[591]
a little bit but there are almost all
[594]
the same so they're very swappable if
[597]
you wanted to get a switch from the
[600]
recibo to the oak style in fact as you
[603]
can see these are the this is the XJ 1
[605]
this is the WJ 1 you can see they're
[608]
identical in diameter spline count there
[610]
is the exact same part there you can
[612]
have the same part number one 905 six
[614]
they both have it stamped right there so
[618]
as far as determining compatibility for
[621]
your swap you don't really have to worry
[622]
about the front shaft too too much now
[625]
additionally um you'll notice they all
[628]
have a breather tube in the same exact
[630]
place because again looking at the back
[632]
of these is this is the same part
[633]
basically something they may have
[635]
different though right here is the shift
[639]
selector sensor so on a vehicle with
[642]
like the two three one or the two four
[644]
two that came in the XJ and the W J and
[646]
the TJ if you're in part-time if there's
[650]
a little light that goes on in the dash
[651]
or if you're in for low this is the
[653]
sensor that tells you the two four seven
[655]
has no need for that so you see it's
[656]
completely missing now when I put this
[658]
in my Jeep this sensor is going to be
[660]
there but I don't believe the thing to
[661]
plug it in is going to be it's only four
[664]
wires I believe
[665]
wanted to I could probably figure out
[666]
how to wire it up I have read
[668]
walkthroughs where people did learn how
[670]
to wire it up I'm not gonna miss it I
[672]
will just do it the old-fashioned way
[674]
and look down at the shifter and figure
[675]
out what I'm in but it is doable to add
[677]
this to a vehicle that didn't have it
[679]
like this but for my purposes I'm
[681]
probably not going to moving to the back
[683]
of these cases or where things really
[684]
start to look different and these are
[686]
this is where you easily visually
[689]
identify a case if you see it out there
[690]
in the yard for starters you're gonna
[694]
notice on anything that came from an XJ
[696]
or a four liter WJ it's gonna have a
[698]
speed sensor here on the v8 WJ the speed
[701]
sensor is in the transmission in the
[703]
five four five orfe transmission so it
[705]
doesn't need a speed sensor that doesn't
[708]
mean you couldn't use this transfer case
[710]
in this vehicle and we'll get to that in
[712]
a minute
[712]
obviously the most useful thing for
[715]
identifying these transfer cases is the
[716]
identification tag it's done right here
[719]
on the back of every single new venture
[721]
new process case and it's got a ton of
[723]
information on it if it's read like this
[725]
one that means it came from the factory
[728]
if it's got a blue ring around it it
[730]
should will likely say Mopar somewhere
[732]
somebody had it replaced at the dealer
[734]
at some point I actually have a four
[736]
liter WJ on the driveway that has a blue
[738]
one because the previous owner must have
[740]
blown up the transfer case had the
[742]
dealership put a new one in so you see
[745]
that blue ring it's still the same setup
[746]
the exact same case just means Mopar put
[749]
their own tag on it that's really all
[750]
there is so you're looking at this thing
[751]
the first thing you encounter is two
[753]
four seven J that's the case
[756]
identification number that's what this
[758]
is now each of those digits means
[762]
something I'm not going to go into it
[763]
here because I have a 20 minute video on
[764]
it but if you want to know I can not
[766]
only tell what transfer case it is but
[768]
to means something for means something
[771]
and seven means something it identifies
[773]
the application and the operation of the
[779]
case so I've got a video I'll link it up
[781]
in the corner if you're interested in
[782]
that underneath that you have assembly
[784]
number and serial number and below that
[786]
you have the gear ratio a lot of people
[789]
hit me up and say hey I have that -
[790]
seven - transfer case no you don't you
[792]
have a two four seven that has a two
[794]
seven two gearing to my knowledge and I
[796]
am pretty knowledgeable in these case
[798]
is the only two numbers that really
[800]
matter are the model number and the
[802]
ratio number
[804]
neither of these actually tell you
[806]
anything useful there's nothing hidden
[808]
in there that's gonna give you more
[810]
information about the case after that on
[812]
the back of the case you have the fill
[813]
plug and the spill plug the way you
[815]
change the fluid in these is you drain
[817]
it all out of here and then you fill it
[819]
up until it's coming out of here here's
[821]
the thing these drain plugs are steel
[823]
this case is aluminum what do we know
[826]
about the different metals dance alright
[829]
does crazy things I've seen people strip
[831]
these out break things so what I always
[833]
say is when you're going to do a fluid
[835]
change take your fill plug out first if
[837]
for some reason you can't get your fill
[839]
plug out at least you still have fluid
[840]
in your transfer case nothing's worse
[842]
than you get the spill plug out and then
[843]
you can't get the fill plug out and now
[845]
you're beat because there's no fluid in
[846]
there so I have seen these things do
[848]
some crazy things
[850]
make sure you use the exact right size
[853]
allen key I can't remember offhand what
[855]
it is I'll write it somewhere
[857]
additionally this two four seven uses a
[860]
viscous coupler it's essentially a
[862]
limited slip very similar to the
[864]
verilock differentials that W J's use so
[867]
it uses gear oil with friction modifier
[870]
in it just like your transfer your
[871]
differential would whereas most of these
[874]
transfer cases use automatic
[875]
transmission fluid two four two two two
[878]
three one but I'm not sure about the two
[881]
four nine I can't remember I'll write
[883]
that down there too
[884]
but make sure you know what fluid goes
[886]
in your case most are gonna take ATF but
[888]
if it's one of those all-wheel-drive
[890]
transfers power on demand type things
[892]
there's a good chance it takes something
[894]
else and this information is true also
[896]
of the newer cases that went in some of
[899]
the newer jeeps with electronic shifting
[900]
it's the same case it's just being
[901]
shifted electronically alright let's
[903]
talk about the tail cones the output
[905]
shafts and the drive shafts that go with
[907]
these this is in my opinion the hardest
[909]
part of the swap now first of all these
[911]
tail shafts are great for identifying
[912]
the transfer case anytime you have a
[914]
rubber boot like this you're looking at
[916]
a two for two or two three one for the
[917]
most part anytime you're looking at a
[919]
conical hard tail like this one you're
[921]
looking at either the two four nine or
[923]
the two four seven those are the all
[924]
wheel drive transfer case is found in
[926]
the Grand Cherokee additionally there's
[928]
another type that you may encounter
[930]
it kind of looks like this with instead
[932]
of having a rubber boot it's got a long
[935]
hard tail shaft huh insert joke barrack
[938]
slip yoke those are usually your HD case
[940]
is either a 242 HD from a grand cherokee
[944]
between i think o 2 and o 4 or something
[946]
like that or a 2 3 1 HD out of a Dodge
[949]
truck now those are highly sought after
[951]
they have the same function as the light
[953]
duty version of each case but they're
[956]
much beefier they can handle a lot of
[957]
abuse so people look for those I am
[959]
gonna talk about the HD cases in a
[961]
minute but for now we're gonna focus on
[962]
the light duty cases and the two four
[965]
seven two four nine now inside this tale
[968]
is obviously the output shaft this is
[971]
what spins your rear drive shaft
[972]
now these tails are so vastly different
[974]
it doesn't look like there's any way
[976]
they could use the same drive shaft but
[979]
in reality they're both 27 spline output
[982]
shafts and they both will use this is a
[985]
chunk of drive shaft but they both will
[988]
fit the same drive shaft come on don't
[994]
make me look dumb hey there we go now
[997]
what that means is there's a good chance
[998]
you can use the drive shaft that's
[1000]
already in your Jeep but we have to
[1001]
figure out is length and here's what I
[1003]
mean from the base of this plate we've
[1006]
already decided that the rest of this
[1007]
case is basically identical so this
[1009]
measurement will be accurate from the
[1011]
base of this plate to the end of the
[1013]
output shafts what's called seven and a
[1014]
half inches all right now on the 242
[1017]
that same distance is let's call it
[1020]
eight and three-quarters so that's
[1021]
significant we're at seven a half eighty
[1023]
three quarters were an inch and a
[1024]
quarter off so because this transfer
[1026]
case is longer the drive shaft that's in
[1028]
my Jeep now may or may not actually fit
[1032]
now these are slip yokes so what happens
[1034]
is this drive shaft is splined on the
[1039]
inside and it fits on there and as your
[1042]
jeep moves up and down your suspension
[1044]
this slides in or out to essentially
[1046]
make the drive shaft longer or shorter
[1048]
now the question you have to answer is
[1051]
does that travel allow for the
[1053]
difference in size I'll give you one
[1055]
example
[1057]
my 2000 WJ has lifted three and a half
[1060]
inches in the rear
[1060]
I also swapped the two started the dana
[1065]
35 which is a short differential for a
[1069]
dana 44 a which is a long differential
[1071]
now what that means is I had to my did
[1074]
my driveshaft now needed to be shorter
[1076]
because it was lifted it didn't matter I
[1078]
was able to use the same drive chef I'm
[1081]
not sure for this swap yet if I can use
[1084]
the same driveshaft now this case is
[1088]
what we decide an inch and a quarter
[1089]
shorter because my jeeps not lifted I'm
[1092]
not sure if my new drive shafts gonna be
[1093]
too long now even the stock driveshaft
[1096]
from my other WJ is a bit shorter so it
[1099]
may get sacrificed to this Jeep this is
[1102]
what I'm talking about with the
[1103]
misinformation or incomplete information
[1105]
if you ask five guys if my driveshaft is
[1110]
gonna work only have five different
[1111]
answers you get guys oh I've done the
[1113]
swap and I use mine now I did the swap
[1115]
and it wouldn't work so unfortunately it
[1117]
seems like you kind of have to do all
[1121]
the research you can on your specific
[1123]
vehicle and then you kind of just have
[1126]
to try it everybody told me that I was
[1128]
not gonna be able to fit my stock
[1129]
driveshaft
[1130]
on that other Jeep and I did I didn't
[1133]
have been wheeling within its
[1134]
articulated and doesn't hit and it's
[1135]
fine it's perfect now there are other
[1137]
options some people trim these output
[1139]
shafts and drive shafts usually it's
[1142]
just a little bit you have to now real
[1144]
quick we'll talk about the HD cases the
[1146]
242 HD is probably the most sought after
[1148]
transfer case for Grand Cherokee guts
[1151]
for Rango guys it's the two for 100 R
[1154]
which has a super low gear it's the
[1156]
transfer case they put in the Rubicon
[1157]
it's beefed up and it's got a super low
[1159]
gear you can find one of those I highly
[1162]
suggest you buy it even if you don't
[1163]
need it because it's worth something to
[1165]
somebody somewhere
[1165]
the 242 HD is something that a lot of
[1169]
people look for in the WJ now here's the
[1171]
thing the spline count is different it's
[1174]
got a 32 spline input shaft so you know
[1177]
you're gonna have to swap the input
[1178]
shaft it also has a completely different
[1182]
back-end and none of the other stock
[1185]
drive shafts will fit with it so you
[1188]
need the rear drive shaft from the
[1190]
vehicle
[1191]
that had the 242 HD in it if it's a
[1193]
Grand Cherokee I've heard people suggest
[1196]
that they put two for two HDS in dodges
[1199]
I've never ever seen anything to confirm
[1201]
that but if it's true if you ever find a
[1203]
Dodge 1500 with the 242 HD and you
[1206]
decide to pull it you're probably gonna
[1208]
have to get a custom drive shaft or find
[1210]
one from a WJ with the 242 HD what they
[1213]
did put in dodges were two three one HDS
[1217]
and again since that transfer case never
[1220]
existed in a jeep you're probably going
[1222]
to get a custom drive shaft made but
[1224]
chances are if you're doing a big swap
[1226]
like that it's probably because you're
[1227]
putting it on a heavy-duty off-road or
[1229]
maybe you want you know slip gieok
[1231]
Eliminator and all that stuff anyway all
[1232]
right that's enough talking about it
[1233]
might as well get to it
[1234]
let's rip down the two for two first
[1237]
thing you're gonna have to do is go
[1238]
ahead and remove the front two
[1239]
driveshaft yoke you need that removed
[1241]
and it's easier to do now next I can
[1244]
remove this plate oh man oh boy these
[1249]
are definitely locked tightened in if I
[1250]
recall that's why we're having trouble
[1253]
come on
[1254]
oh these things are real fun to argue
[1257]
with blown on a bench but it's all it's
[1261]
gonna shake I recall yeah he's had some
[1266]
kind of Loctite on them so we will
[1269]
Loctite them again at the end already
[1271]
now this piece is RTV Don even from the
[1274]
factory that's how they're supposed to
[1275]
be there our price now like I said this
[1278]
is an aluminum case you want to be very
[1280]
careful about warping or breaking it so
[1282]
there are little pry points in the side
[1284]
and you're gonna want to get a
[1286]
screwdriver or a tiny pry bar in there
[1288]
and kind of Jimmy Jimmy Jam it jiggling
[1290]
like that that way ah there we go
[1293]
just take it nice and easy so that
[1300]
you're sure you're not gonna break
[1301]
anything now when you pop this guy off
[1304]
you'll notice there's a divot in the top
[1307]
this needs to be oriented the same way
[1310]
when it goes back on as we you just took
[1312]
it off this hole needs to line up with
[1314]
this hole there that's how it moves oil
[1317]
around now what you're looking at is the
[1320]
input shaft the input shaft bearing
[1322]
there are a couple of snap rings here
[1324]
we're gonna have to contend with I do
[1326]
not have good snap ring pliers so I'm in
[1329]
for a fight I recommend you go ahead and
[1331]
get good ones before trying to do this
[1332]
it's just gonna make your life a heck of
[1334]
a lot easier all right what's up Pope
[1335]
it's actually the next day I went out
[1337]
and I bought the proper pliers last
[1340]
night my camera died and then the SIM
[1342]
card or SD card was all filled up so I
[1345]
took that to mean that God was telling
[1346]
me to go ahead and buy the right tool
[1348]
for the job so for this this is not a
[1352]
snap rings technically a locking ring so
[1353]
you need these little flat nosed guys
[1355]
here I never had them for but now I do
[1358]
and Wow so much easier than doing it the
[1360]
wrong way so moving along now we can
[1365]
begin to split the keys having removed
[1368]
the front yoke and the input shaft
[1372]
locking ring all right as you will see a
[1375]
spilled ETF all over the place which is
[1376]
just awesome that's my favorite smell in
[1378]
the world
[1379]
once your seals are off the front your
[1383]
case is wide open so make sure you're
[1384]
not getting any junk in there and be
[1386]
careful because that last bit of fluid
[1387]
can come out we're now ready to split
[1388]
the case these cases are held together
[1390]
with 15 mil six-point bolts and 10 mil
[1394]
12-point bolts only twelve point I seem
[1396]
to have around is this crazy wrench that
[1398]
I've modified for doing a 4.7 liter
[1403]
hydraulic lifters but whatever you're
[1406]
going to work your way around the case
[1408]
taking them all out
[1409]
these cases are RT vide together from
[1412]
the factory and they do a factory pride
[1414]
points so there is a process for getting
[1416]
them out and now we get to finally split
[1418]
the case finally finally finally got to
[1420]
do it carefully aluminum case there are
[1422]
two pints where your screwdriver can go
[1424]
in ones right here and ones on the
[1426]
opposite side what you're gonna want to
[1428]
do is get them in there yeah there we go
[1433]
hear that our TV breaking apart just do
[1436]
it nice and slow
[1437]
little bit on the other side this is
[1440]
gonna make such a mess
[1441]
oh my god seams gonna bleed everywhere
[1443]
I've never been very good at getting all
[1445]
the fluid out of these things before
[1447]
digging in I forgot about the other
[1449]
locking ring in the front there are two
[1451]
locking rings in the front one that goes
[1453]
around the input shaft and one that goes
[1455]
around the input
[1456]
barring if you don't pull that out
[1458]
you're not going to spit this nicely so
[1461]
that's why I was having all these
[1462]
problems it's difficult because it's
[1464]
usually hidden by RTV so you're gonna
[1467]
have to break the RTV up find it
[1470]
obviously without marring anything up
[1472]
but it's right here all righty there we
[1487]
go we'll clean up that old RTV before we
[1489]
put things back together but we can now
[1491]
split our case the way we're supposed to
[1493]
be able to split our case all right
[1495]
you've got all your snap ring lock rings
[1497]
out of the way we're gonna take this and
[1520]
put them aside now we've got our rear
[1522]
output shaft out of the way with the
[1524]
back half of the case this is of course
[1526]
the gear and shaft for your front output
[1529]
here is your gear selecting ring
[1532]
selector fork assembly can be lifted out
[1535]
there was a magnet that goes right here
[1537]
you want to pull that out oh you're
[1540]
gonna want to clean it up the oil pump
[1542]
assembly is on the other half of the
[1544]
case so I'll show you that in a minute
[1545]
just going to go over the back half real
[1546]
quick this is gonna be all covered with
[1548]
shavings as long as no big chunks should
[1552]
be alright
[1552]
whole point of the magnet is yes some
[1554]
metal particulates do accumulate in
[1557]
these cases and if you don't have a
[1561]
magnet in there to catch them well you
[1563]
get it all right once you have
[1564]
everything to this point you're gonna
[1566]
want to make sure there are some plastic
[1567]
guards on the shift fork here make sure
[1569]
nothing happens to those if you've got a
[1570]
rebuild kit you probably have new ones I
[1571]
recommend you put the new ones in now we
[1573]
need to remove this shifter fork
[1575]
assembly on the 2:31 it's easy because
[1577]
it's big and it just slides right off it
[1580]
is not easy on the two-for-two it
[1581]
actually kind of really stinks what
[1584]
you're supposed to do what they tell you
[1586]
to do is right down here in this hole
[1588]
which is covered
[1589]
with this little cap usually it's a roll
[1592]
pin that they want you to use a number
[1596]
one extractor screw extractor to back
[1599]
out I don't know anybody who's tried
[1601]
that method who hasn't either been at it
[1604]
for three days before it happened or
[1605]
just giving up some people end up
[1607]
drilling big holes in their cases
[1608]
there's a much easier way
[1610]
don't don't mess with that hole I would
[1611]
not recommend it right here this is a
[1615]
7/8 I don't know what the technical not
[1617]
a name for this now you can remove this
[1621]
when the case is put together still and
[1623]
that would make it much easier but I was
[1625]
busy focusing on you folks filming so
[1627]
now I'm gonna have to argue with it but
[1629]
you remove this and then you can wiggle
[1631]
it out I'll show you how in a second
[1638]
remove it this is kind of holding the
[1650]
shift' plate in place it's got a spring
[1654]
and it's also got another little piece
[1657]
on the end I recommend taking it all
[1658]
that way it's not left rolling around
[1660]
anywhere there we go when you hear this
[1663]
satisfying clunk when you shift gears
[1665]
you can thank this little spring and cap
[1667]
setup I can't remember what it's called
[1668]
might be a detent I'm not sure now that
[1673]
we're there we've loosened this plate
[1676]
enough that you should be able to sneak
[1679]
a screwdriver down in there and kind of
[1684]
pry what you're doing is this is
[1686]
retained inside the slot of this plate
[1689]
here you're kind of prying the two apart
[1692]
now I know this seems a little bit
[1693]
sketchy but believe me the other method
[1696]
is worse Google 2 4 7 roll pin removal
[1699]
and just read some of the nightmare
[1701]
stories on the forums I mean guys are
[1703]
drilling holes in the side of their
[1704]
cases
[1705]
to try to get to it most of them about
[1707]
you don't hear about very many people
[1709]
using the roll pin method that actually
[1710]
get it oh the joys of making videos on
[1713]
the work I do in the garage so I finally
[1715]
get it out I look over to make sure the
[1716]
shot is still framed and I realized the
[1718]
battery has died so I'm not sure yet how
[1720]
much of that you saw but I assure you
[1722]
no camera trickery or anything like that
[1725]
whoops that's upside down you just you
[1728]
work it to a point where you're able to
[1729]
free it from the plate and then you kind
[1731]
of get under this wing and on this
[1733]
little gear tooth right there and you
[1735]
just give it a little and it Jimmy James
[1738]
itself right out you're gonna be careful
[1740]
there's some plastic sleeves here to be
[1741]
careful of these guys you don't want to
[1743]
lose those little plastic shift pads
[1748]
there so oops now that that's done and
[1753]
that is the piece that gives two for to
[1755]
swap owners the most heartache
[1759]
all right then this piece will come out
[1762]
with a little bit of Jimmy Jam and again
[1764]
there are plastic feet on these you want
[1768]
to put this stuff aside I know we got a
[1769]
lot of pieces now but trust me it all
[1772]
goes back together it's not as scary as
[1776]
it seems right here we have our
[1779]
planetary gearset alright this is where
[1784]
the magic happens
[1786]
bring you in a little closer we're gonna
[1788]
free this input shaft alright now this
[1791]
is a three planetary gearset most of the
[1793]
basic transfer cases have a three
[1796]
planetary gearset when you talk about
[1798]
the HD cases they have a six planetary
[1800]
gearset you see instead of spaces here
[1803]
you just have another set of here's
[1806]
they're inherently stronger more metal
[1808]
more contact or beefier alright there's
[1811]
another locking ring snap ring type of
[1814]
guy in there
[1814]
aw it's got a little pride face you can
[1818]
see oh boy
[1819]
right here and right there so nice and
[1821]
carefully we're gonna get him up and
[1829]
work on more out and there you go this
[1837]
is your input shaft this is what all
[1839]
this fuss is about you can see it's got
[1841]
some roller bearings inside there this
[1846]
is what you're swapping to make your
[1848]
transfer cases compatible most of the
[1850]
time this is all you're gonna have to do
[1851]
alright let's take a look at the back of
[1853]
the case
[1853]
real quick you gotta chain right here's
[1856]
your front outputs f2 front yoke would
[1858]
go on here this is the where the input
[1862]
shaft would go the rear output shaft is
[1864]
back here like I said this is your front
[1868]
output shaft we can move that if you
[1870]
want to get the chain there's some
[1873]
roller bearings in here that if you have
[1875]
a kit you probably that's probably one
[1877]
of the ones that you will be changing
[1879]
this one is notoriously difficult to get
[1881]
to a lot of people use strange pullers
[1884]
I've heard of people using bread a
[1886]
number of other things but that's not
[1888]
something we're gonna do in this one I
[1890]
may do another video on how to do all
[1891]
the seals and bearings in one of these
[1893]
transfer cases now right here you have
[1895]
your oil pump pickup on the other side
[1899]
of the case is another slot the magnet
[1902]
that we talked about earlier sits right
[1904]
on top of this so the idea is fluid is
[1906]
being pulled over the magnet metal
[1909]
particulates are getting caught up there
[1910]
and the other nonmetallic particulates
[1912]
are getting caught up in this screen so
[1914]
when you pull this out there may be some
[1915]
gunk on it you can go ahead and give it
[1917]
a little Queen mine actually looks
[1918]
pretty darn good you want to make sure
[1921]
you don't disrupt any of this stuff
[1922]
because obviously you're not gonna be
[1925]
pumping oil in here I've been making
[1926]
very far down the road one last quick
[1928]
note on the back of the case these
[1930]
chains tend to stretch and that's how
[1932]
you can determine how worn out a
[1934]
transfer case is now when they get real
[1936]
worn out they'll actually slap on the
[1938]
bottom of the case and make a noise now
[1940]
you can see that even though this came
[1941]
out of a jeep with 220 thousand miles
[1943]
the chain is really not all that
[1945]
stretched what that tells me is this
[1947]
Jeep was driven in two wheel drive most
[1949]
of its life so even though it has 220
[1951]
thousand miles the power was coming in
[1954]
here going straight through there was a
[1956]
lot of tension being put on this chain
[1957]
by sending power to the front now jeeps
[1961]
that's been off-road a lot in four-wheel
[1963]
part time movies too are locked together
[1965]
that's when the chains start to get
[1967]
stretched and you'll have problems where
[1968]
they're actually hitting the bottom of
[1970]
the case the health of a transfer case
[1972]
can be determined here and this one's in
[1974]
really good shape even though was from a
[1976]
high mileage Jeep it was taken care of
[1977]
and was not abused and I honestly
[1980]
believe this was probably the city Jeep
[1983]
that was driven in two-wheel drive most
[1986]
of the
[1986]
it's life so that's a way already
[1988]
friends as is so often the way we made a
[1990]
plan God heard our plan and swiftly
[1993]
chuckled and threw us a curveball the
[1996]
curveball in this case is that I got
[1997]
into the 2 for 7 this is actually the
[1999]
input shaft and you know it's just way
[2001]
more fascinating than I thought it was
[2003]
gonna be I've never dug into a 2 for 7
[2004]
I've done an extensive reading on it but
[2006]
I think it deserves its own video so
[2008]
we're actually gonna close this video
[2009]
out here we've accomplished what we came
[2012]
to do yes I need to put all this back
[2013]
together but you guys don't need to
[2015]
watch me do that oh this is the gearset
[2017]
planetary gearset from the 2 4 7 sorry
[2022]
this is the planetary gearset from the 2
[2023]
for 2
[2024]
I'm gonna slide the one from the 2 4 7
[2026]
in and the way we're gonna go just like
[2030]
that and see if it's perfect everything
[2031]
spins we'll get our plates and
[2034]
everything in there and I'll be able to
[2038]
slide it right into the 2 for 2 and I'll
[2039]
be in business so I will do a video on
[2041]
the 2 for 7 what I think I'm gonna do
[2043]
since I'm already into this one when I
[2045]
pull the 2 4 7 out of my Jeep we'll
[2047]
dissect that one that way we can do it
[2050]
from the very beginning and really go
[2051]
over it in my reading I noticed there
[2053]
weren't too many good videos on the 2
[2055]
for 7 lots of like hour and 20 minute
[2057]
long tear down sign and I know I'm a
[2059]
little worried but I'd never give you an
[2060]
hour 20 minute long tear down video no
[2063]
one wants to watch that anyway
[2064]
let's close this out here I'm sure
[2066]
there's gonna be lots of questions by
[2067]
all means leave them down there in the
[2069]
squawk boxes I did my best to make this
[2072]
a complete video with the generic basics
[2074]
that anyone would need for specific
[2076]
questions put them down there I'll try
[2078]
to help others in the community will
[2080]
help now that you know the basics you
[2082]
can at least go to the forums to ask
[2084]
about your specific vehicle in an
[2085]
educated way so this right here is the
[2087]
key this is what it's all about at the
[2089]
most basic level just switching out
[2091]
input shafts and then from there maybe
[2093]
you have to mess around with Drive
[2094]
shafts maybe you want to do some other
[2096]
little things I like that anyway um
[2101]
let's close it out there if you liked
[2103]
the video like the video by all means
[2104]
