Is it possible (worth it) to switch a transfer case from a 99 jeep TJ to the right input for a 92 YJ? I blew a transfer case and found one that would work with low miles, but it might be the wrong spline count, I'm not sure. Thanks!
In all YJ's. The 4 cylinder with the AX5 had 21 spline. 6 cylinders have 23 spline.
The only differences are the in the tail housing there is a difference in the way the tailshaft is lubricated. Also the YJ's have vacuum lines from the TCase for the 4wd indicator light. Both of these items are able to be switched over from TJ to YJ 231. I've done this for YJ case to a TJ case.
auto tranny should be 23 spline. Most XJ 231s will be 23 spline. That is, if you can find one. Not all XJs have the 231 case. Double check the tag on the case to verify which case it has. You will want to stick with the 231
