ok heres my deal, I'm trying to find someone who has put a np231 transfer in a ZJ. I am told that it won't just bolt up, I will need a new input gear, fine. heres where things get tricky, I am also informed that the input bearings are all kinds of sizes. so what I need to know is, I have a 1997 TJ 231 that I want to put into a ZJ. what do I have to change in the input side of the transfer to complete the swap. if I had time and space I wouldn't bother asking so many damn questions. I'd just do what most self recpecting people who would try this swap do, and just get one with it. I can not do that at this time. anyway, I also may have a np242 that I can either rob parts from, or swap it in. I still have not found anyone telling me that the either the 242 is stronger, or the 231 is stronger. can anyone help?

P.S. I have not seen that many grand stuff posted here thats why I did not search, but to make everyone happy, I'll do one later this morning.
Two months ago, I took the np231 from my 98 TJ (4.0/ax15) and bolted it up to my friend's 93 ZJ (V8/auto) with absolutely no modifications being necessary. Every aspect was dead nuts on.
The case swap was an easy 10 minute job. Even the shifter linkage lined up perfectly. The only accessory lost was the mode switch.
That ZJ (f&r d44's, 33's, arb, spool) has since been wheeled HARD in Moab and CO with no ill effects on behalf of the 231.
ok cool! now I am trying to transplant my 4.0L 97 TJ 231 into his 4.0L awd grand. as far as I know anyway. got a good way to figure out what tanny he has? I am not good at identifing jeep autos yet. thatsnk for the info, we may pull his t case to find out what he has tomarrow.

ok thanks for all the help you have given me. It seems I can not get used to the fact of being called a newbie. I work on some cars worth more than most jeeps, and I am called a newbie! haha life is strange thanks again
