WELL,,,,,,,,,,,,,,,,,,,,,,, if you dont know the history of the differential,,,,,,, IF it were me,,, I would take it apart and inspect it. Its pretty straight forward. I will provide you with a couple OUTSTANDING post that will shed some light on what your need to know about the inner workings of the rear.

IF,,,,,,, you want a more dependable rear,, you can do the C6 ZO6 parts install. At a MINIMUM,,,,,, replace all the seals that can leak (Both output shaft seals and the seal between the trans and diff.

The drivers side will wobble a bit. Being the longer shaft, it gets additional support from a caged needle bearing inside the case once the axle is in.

Broken belville spring is a distinct possibility, mine was that way when I took it apart.

At 100k miles, my car had one cracked belville spring and one completely shattered belville spring. My posi didnt work at all.

New C6 parts installed and its good to go again.
