(It really did sound like the tires slipping and the clutch plates in the diff rubbing because it was just too tight.) After getting it back I'm almost sure it drives better and corners easier. Besides the sounds and tightness in slow cold corners I think it was binding a little all the time because now it seems to just glide around turns with the greatest of ease. I hate to think how much wear I might have been putting on the diff and the rear tires all this time by not taking it in sooner. Everyone that suspects that they have the problem might want to take it in. I have the V6 LS2 with the manual. I think the automatics don't have the LSD at least not the V6's. Here's a photo of the labels from the fluid and the additive that they put in and the back of the additive bottle that I think did the trick!

I had this done too on mine about two months ago and the noise disapeared however yesterday it started again so I will be taking it back for a second go around.
