Question WJ Transfer Case Yoke Swap - CV to U-Joint

Sorry, for some reason I can't search the forum at the moment, but can anybody point me to a guide, or a video on how to swap the U-Joint/CV Joint shaft for the front drive shaft(mainly changing the CV yoke to U-Joint Yoke on the transfer case)? I've read it's easy, but I wanna see whats involved so I know what to expect. Thanx in advance.

Remove the drive shaft, take out the 29mm nut on the yoke, pull out the CV yoke, slap on the New yoke tighten the bolt.
Done!

Or....

Replace the drive shaft that uses the U joint - that was considered an improvement to the CV joint. Implemented around 2002 and less costly to repair! Just a thought!

Thats it? Its just one nut, eh? Ever heard of any instances of of the yoke sticking/not wanting to come out?

If it doesn't wanna come out grab a rubber mallet and smack it a few times. Lol.
For the last four days I've been playing with the exact same part.
Check out my post on the 241 transfer case swap thread.

I had to use a two-jaw puller after removing the nut. The CV yoke came out pretty smoothly with just a little tension, then the puller fell off and i slid it the rest of the way out by hand. I slid the U-joint yoke on the spline of the T-case and tightened her down to torque spec. I can't, for the life of me, remember what that number was. ChrisHager has an excellent write-up on this subject somewhere......

I also made sure to put her in 4WD full time before I put her up on the lift. I didn't even have to use a tool to hold the spline from turning. The T-case yoke swap is the easy one to do. The yoke swap at the front differential was slightly more challenging. I had to do both because I was converting from rzeppa/rzeppa to the Double Cardan.

I’m in the process of doing this exact swap on my 2003 grand Cherokee Laredo but I’m having a problem figuring out what yolk I’m gonna need on the transfer case I’m not sure what transfer case I have. Apparently there’s a 32 spline A different 32 spline specifically for the 241J a 26 spline and a 10 spline (I am certain I don’t have the 10 spline) there is also three different joint sizes 1330 1350 and 1310 how do I figure out exactly what I have so I get the right part?

Just get parts from another WJ that you need to put on your WJ. Then, you'll know the right parts are on your WJ. Any T-case yolk from a WJ will fit any other WJ. WJs don't have a 241J transfer case. I hope this helps you, buddy.

The yokes for the front driveshaft are all the same on WJ transfer cases. (v8 to V8, and I-6 to I-6). The rear output shaft splines are the ones that chnage. Look on the back of the transfer case for a silver and red decal that has the transfer case model stamped on it. This will help us know what your dealing with. Also, if you have AWD, then you have the 247 transfer case....

OK I found the tag it is definitely a 242. Yes the information about the splines did help the only issue I’m coming across as they have a lot of yolks available for the 242 but apparently I have to get a specific one for the WJ because the splines are tapered at the end which is the only difference between tge WJ 242 transfer cases and other 242’s or so I’ve read. Also I just watched a video where a guy pulled one off a different 242 without the tapered splines and he just grinded them down and it worked fine I would preferred to get the right part though lol. Also I tried to just find a WJ with the pieces I needed but with no luck I was able to find a DC Front driveshaft from a salvage place they unfortunately did not have the yolk that came with it. I’ll find one. If not I’ll get a new one but I’m really not trying to not spend $80 on a new yolk especially since the driveshaft is only costing me 60 bucks

There are two different spline counts possible for the front output of the tcase. 26 spline is supposed to be more common but 32 spline ones exist as well. If you have a 32 like I do you can buy this yoke for a JK which fits perfectly. https://www.rockauto.com/en/moreinfo...pt=16612&jsn=1

I’m only asking because it doesn’t have a picture of the back of the splines I need to make sure they have the tapered end required to put on a WJ
