Has anyone heard an odd noise coming from the back of the car when going slow around corners. I can not tell if it is the diff slipping maybe the clutches inside? Or the brakes making squeaking noises. Its odd that it only happens when you are turning hard corners in a parking lot or turning into the drive way.

 

Change the diff fluid and make sure you add posi additive.

 

Mine does it also it sounds kinda like a clunking from the rear.
I've heard everything from "You are low on LSD fluid" to "it's normal" I am living with it since I am not low on LSD fluid.
Good luck let us know if/when you fix it.

 

The car is full of fluid and it only has 35,000 miles on it original I thought it sounded like it came from the diff and not the brakes I just wanted to see what others thought or if any of you are having the same issue. I am considering a gear change to 3.73s I will make sure I add the correct amount of Limited slip stuff.

 

My car had been making a whirring noise when doing slow sharp turns, for a long time. After reading on here i changed my rear end fluid with some sythentic and posi additive, not gm, just advance auto stuff. I think it was called somethign like Trans-x. Anyways, that solved my problem, i do suggest when putting the rear end back together, use the rtv sealant. I did not and now will be squirting some around the edge to helpstop a minor leak
