I am so lost and confused. I have an np231 in my 95 xj (auto) that sounds grenaded, wont stay in 4x4 , and needs to be repaired or replaced. any pointers on where to start?, IE, is it even worth rebuilding one (i know, hard to say w/out seeing whats goin on inside it) or should i just find a pickNpull and swap. if so, what will fit? and or, what can i expect to find inside mine and is the rebuild even worth tackling?

cost, as always, is absolutely an issue.

I think if you rebuild one, go to picknpull and get one and rebuild that, Keep that jeep driveable until your ready to put it in

and with that in mind, what fits?

Anything above 1990 I have a 2000 in my 89 behind a nv 3550 everthing from my 89 231 hooked right up.

sweet. that makes the list at PnP a little longer.

B4 removing one I suggest pulling drain plug ans sticking finger in and make sure theres no metal/garbage sitting in the bottom . Be a real pain to bring home one with unseen issues.

so many bad jokes in here...

If you're getting a 97 and newer tcase, I believe the driveshaft is a little shorter.

ill make some measurements and take pics before going. ty
