A jack under the trans after removing the crossmember is a good way to adjust the level prob not a good idea to just let it hang on the motor mounts

I have a 93 JGC limited and I can get a transfer case from a 95 JGC limited and was wondering if it would work and if so how hard would it be to do it.

bump: tag says 231J but it doesnt have the rubber boot. i know i gotta swap the input shaft, but does anybody think it will fit without getting the driveshafts lengthened/shortened?

Have read that the external and internal slides are 1.5" different but thats 231 vs 231

Mesure from case to end of shaft see what that is compared to the one in your jeep
my 249 ds internal was shorter then 242 external luckly I picked the ds from the doner jeep get it done and measure for the ds you need I got a few laying around i'll get length and pics posted up incase any one wants one on the cheap

231 J signifies that it is a Jeep transfer case. All Jeep transfer cases have the letter "J" proceeding the model designation. You DON'T want the rubber boot (external slip yoke) for the easiest swap in any ZJ (unless it has a prexisting 242 with an external slip yoke).

Want to swap an NP242 or NP231 into your ZJ? Here's how:

mainly because no one wants to shorten the driveshaft and noone knows what the number of the output seals are or where to ge t the boot!!

nothing i cant do--i'l pay myself $50/hr labor!!

the only thing you cannot do, is that which you have already accepted defeat!

many people search for god in the eleventh hour, only to die at 10:30

98 ZJ wants a 242

Hey nice thread you wrote, really insightful. I have a 98 ZJ 5.2L Limited and want to remove the transfer case that's in there and out a 242 in there. Any chance you could build that specific T case for me? Let me know asap. Thanks

just a question. would a 242 from a wj swap into a zj?

'96 ZJ Orvis 5.2L (Mossy Oak Edit.)- UC+2" BB, Thrush Turbo, 2 12s, Lots Of Stickers
You drive a tj, we drive a zj. We have more power while you get more shower. We get the v8 while you get there too late. You have 2 doors well, we have 2 more. Ours costs a grand while yours has a price we cant stand.

Anyone know at which point exactly i measure from to determine input gear length? Seal, bearing face?

I know what i need, and have aquired two inputs but need to verify it's an .0840" input.

Redneck - No, it won't. It'll physically fit and function, but the WJ 242 doesn't have a speedo sensor provision, as WJs get their speed from the ABS tone rings.
