Take it to your dealer. you need limited slip additive in your diff.
There is a TSB (Technical Service Bulletin) on this (involving Cadillac XLR's and C6's). Their first attempt to fix it will be a drain/refill with additive (per the TSB). This was done on my 2005 and quieted the rear end for about 1000 miles (and based on what other folks have written, the drain/refill never fixes the noise long term). The real fix is to replace the clutch packs in the rear end (also per the TSB). This was done to my car (after the drain/refill failed) and no issues since (6000 miles ago). Do a search and you can probably find a copy of the TSB to print and take to your dealer.I am new here and thought I would see if anyone has had the same problem I am having. I know the older vetts had the slip-posi track rear end. In my C6 while going around a corner slow either left or right I am hearing a noise from the rear end. Its not really a grinding noise but almost sounds like something is rubbing. I think it has something to do with the slip posi track but am not sure. It is starting to drive me crazy. I just wanted to do some research on this before I take it back to the dealer. If anyone has any advice that would be great.
Thanks to all in advance

TreCool...delete some of your Private messages so I can reply to you....Just took mine in to get that fixed yesterday. Problem solved. :thumbsup:
Thats correct...but then in April they deleted that bulletin. It used to say to remove the left side diff cover to get all the old fluid out, then refill and add a bottle of friction modifier. If noise returned, replace the clutch packs. That bulletin is gone. The new bulletin simply says to remove drain plug, drain the fluid, refill and add TWO bottles of friction modifier. Apparently they're so sure that will fix it that there's no longer any mention of replacing clutch packs.There is a TSB (Technical Service Bulletin) on this (involving Cadillac XLR's and C6's).
