How would you know if there is something wrong with your LSD?
I'm hearing some squeaky noise coming from my rear every time the road is uneven, a sudden stop and especially backing out of my driveway. I don't know if its my shocks or the LSD. Lets say it is my LSD, would you guys think it would be covered under warranty?

Thanks in advance for any input

 

I would expect any LSD problems to be covered under warrany, but it is far more likely that this problem is related to your springs or shocks. It could also be your brakes. Try pushing down on each of your rear corners and see if you can reproduce this problem. If you hear something, it is the springs or shocks.

Otherwise, have someone else back up the car (thereby reproducing the problem) while you stand next to it and try to isolate the source of the sound.

 

The sway bar bushings must be greased from time to time, or they will squeak. All you have to do is loosen the brackets enough to allow the grease gun's needle fitting between the rubber and steel, and give it a squirt. If it gets better or worse depending on weather conditions, I would try this first.

 

Suspension pieces can account for a large percentage of noises in the car. Like Gernby said, grease your swaybar and check your shocks/springs. I bet that will solve your problem.
