Transfer case noise

Factory uses a paper gasket but I've never put one back in. Just hope that ATF is coming from the t-case and not out the back of the transmission!

On a somewhat related note I happen to have an AX-15 for sale. The NP231-J attached to the back is the same internally as the one you have except it's clocked different so you'd have to either split the transfer case and use the front casing from your XJ, or drill new holes. Or find another one.

Good news! I swapped the T-Case on Saturday, and problem solved! Once i took it off, I took of that input seal housing off, and could see that the imput shaft bearing was the issue...all the ball bearings were pitted like hell! Has anyone ever replaced the input shaft bearing on one of these before? It doesn't look half bad.

Usually the price of getting the parts and the the time of the rebuild isn't worth it, you can just buy another one for $80-150. That's my take on it anyway unless you have one that's tricked out with SYE and HD chain kit already. Transfer cases are pretty basic so if you wanted to do a rebuild with a little research into parts it would be fairly simple. Don't forget the plastic tips on the shifter fingers, and no don't let the parts guy tell you they are all the same.
