Ok, I was changing my rear end fluid today & found a few pieces of metal stuck to the magnet. The piece looks like its some kind of retainer for the limited slip clutches, I can see where one is missing & a few plates are not lined up good. It looks like I can just replace the plates & retainer clips. Who sells parts like this? I called the dealer, gave them the VIN & they dont show the car having a posi or any parts for it. I got a build sheet & it does show it came with a posi. Or the only way to get these is buy a carrier?

 

If you did not buy a SLp upgrade to the posi, then you have the OEM torsen. There are no clutches or plates, its a worm gear drive. if it fails the entire thing is replaced.
If you spent for the SLP upgrade you got a auburn. You have cone clutches and if it fails you have to replace the entire thing.
So you are screwed either way.

 

Have you done any work to the rear since buying the car? There might be an Eaton Posi in there that has carbon clutches...
