Sounds like a loose drive chain. Is it an NP231 or 242? Was it in 4WD or 2WD?

I'm not sure which one it is it's an 87 cj pioneer with the 4.0. It does it in both 2wd and 4wd. Just when putting it drive and reverse and that's the only time it does it.

It's probably not fully engaging but hey it's a CJ question on an XJ forum... Unless you made a typo

My 1998 xj with an NP 231 made a similar noise. I dropped the front ds (four 5/16" nuts) and rotated the front yoke back and forth. It was so loose, you could hear the chain slapping around inside.
