Rear end clunk

[Milvetmac]

After pulling the rear end apart 3 times I finally found the spider gears to have a very small amount of play causing an intermittent kick in the butt on acceleration from a stop.

And did you get the play back in spec? Where did you shim it?

I replaced them and have not had the problem since, I do think the severity had something to do with the fluid as well... the diff service was a while back and I don’t think the correct fluid was used, put the mopar fluid back in with an overhaul kit and re used the factory gears
