I had a similar noise when reversing ( the car drove ok otherwise ) and it was my limited slip clutch plates ( that had shattered ) spreading there goodness all through out my ring and pinion...necessitating in a diff rebuild.
You probably have better luck than me so I wouldnt suspect thats your issue.

Im no expert so best someone else chimes in....If its slip plates that have gone bad, yes, diff needs to come out.. Has it recently had a diff oil change? Really need to have someone at a workshop analyze the fault for you and go from there.

Problem is there's no mechanic specialized only on american cars.All they can do everything and no one can do anything
They do Fiat and other car,but if you bring them an american car looks like if you bring them a space ship

Limited slip rear ends usually require an additive, affectionately known as "gorilla snot" to keep the clutch plates from sticking. Plain old diff oil will not have this. Some of the better aftermarket brands are fine without the additive as its already part of the formula. Best to check with a dealer. Without it you will get a clicking sound when you make tight turns. This will destroy your diff it is not corrected.

I would recommend using the GM brand. I tried aftermarket but had much more noise and I was using Amsoil.
