I am still trying to diagnose a knock in the rear end of my 1993 Z28. I took the diff cover off and rocked the tires back and forth. The normal play is there in the ring and pinion, but there looks like there may some extra slop in the side and spider gears. The teeth are all there, but the play seems excessive to me. In park, with the car on the ground, you can roll it back and forth and hear some clunking.

Any input?

Thanks a ton,
Rob

 

That seems like a lot of play compared to what mine was. Mine would move a hair and stop. If there was suppose to be a clunk noise in the video i didn't catch it.
