I have noticed a couple times when i would back out of my friends driveway (down hill) i would here like a big bang /clunk noise. It seems like its coming from my rearend almost like the axles and pinion ring lock up for a second. I also noticed that when i was in the snow only one wheel was spinning could my limited slip be toast. I have a warranty still so i will prob be bringing it in by the end of the month but would like to see what you all think.

P.S. I have the front clunk noise which i need to get the clunk washers.

 

I would take it to dealer and let them check it out/
