well, im familar with np231 (had a yjfor 3 years, went through 2 engines, 3 trannies, and 2 t cases kicking the shit out of it) and i know how stretched chain sounds.... also i did put 4* shims, the only thing that i did not do, is remove my tcase drop brackets which are 1". I removed my Front DS(after recent wheeling noticed my aluminum bottom bump stop loose and my exhaust pipe bent in) to eliminate all the noises while in 2wd. and it was still making that noise. Also all that was done by a trusted mechanic that i have been dealing with for the last 10 years, and all my companies pickups (10) are serviced there.
....... Tranny X-member is wet, but you can not see any apparent leaks... , when checked T case fluid it was OK. ... ... so my question is, if thats AA parts that make noise, did anyone have that happen to their XJ ? Would a rebuild of my T case have to include brand new SYE kit from aa? well, not the whole thing, but the internal shaft....>???? if not, and if all AA parts can stay the same... where to buy a GOOD rebuild kit, for how much? before asking if it is too hard to rebuild it yourself, i will search the forums
PPPP oh... its a 98 with auto, and about 150k of kilometers, so ... around 95? miles? something like that... when i removed my stock shaft @ 135km when bought, it still had stock u joints...
so... no.. it was never wheeled
