Np 231

I got a jeep yj and the guy said he took out the front driveshaft to replace the U-joints but snapped a bolt in the yolk but I got new yokes but now the transfer case makes a loud clunk I think it's the chain slipping because it's loose and broke a few teeth doing it so I was wondering if anybody knows were to get a used one for cheaper money it's a 1990 jeep yj inline 6 258 5 speed I think it has a 23 spline input shaft or something like that any help would be greatly appreciated! Thanks

I've been in the same predicament with mine. I bought a used np231 from a '97 wrangler on Craigslist for $75 only to find out the input shaft splines are different on those compared to the YJs. Plus I took it apart and found a bunch of broken pieces in it too. My next option is to buy a master rebuild for $200 online and rebuild it myself. Ive now learned from experience that you probably shouldn't trust buying a used TC. Think about it, why are they selling their TC anyways? My seller gave me a great reason, I believed him, and he got my money.

So, spend a little more than twice the amount and get an almost new TC or $75 and run into problems soon.
