Changed my limited slip differential oil on the rear. UH OHHHH

The Gray material puzzles me . Friction additive? There any contamination of the grease with water ??

Looks like a factory coating of internal parts perhaps. (removed from the bolts and caps in this pic when I cleaned it all up inside)

Since you don't know exactly where that came from or where other pieces may still be inside, you risk blowing out the pinion bearings, carrier bearings, or a piece getting tossed up with the lube, staying on the face of a gear and locking it up. I had bearing parts get tangled up in a transmission gear and lock the thing up solid - couldn't move it an inch.
You may go weeks or months, but if a piece like one of those smaller ones gets in the wrong place, it may lock it up.

Your truck, your call, your risk. Mine would get trailered to the dealer and they'd get handed those pieces.

PS - grinding and squeaking is not normal - you need a new dealership. These should be quiet as a mouse. Never in my life had a limited slip that made any noises, but I've worked on some where the pinion bearing blew out for no reason and locked up so hard the car slid to a stop. I found the last person to work on it totally screwed up the limited slip assembly when I dug deep into it.

This. Get it fixed and dump that dealer.

**UPDATE** Took it back to the dealership and they agreed to fix it for me. These are the two pictures that they sent me and said that they are ordering a replacement slip differential. I did ask them if I could switch to the truetrac.. but they said that they only replace broken parts with factory parts. The limited slip differential is on backorder. They’re also ordering two new rear axles. What do y’all think about these two pictures?

I am trying to figure out what I am seeing with these 2 distinct colors in the pin on this spider gears. Like something was chewing on it . Something shifted over..it definitely is broke .

I know! It’s hard to tell in the picture and I haven’t seen it in person. But it’s definitely shiny on that pin and almost looks like it has channels on it.
