Got the cover off the 94 AWD G80, GT4 rear. The ring teeth seem OK as well as what ever else I could see. The fluid was full, sort of amber color when I checked it, but foamy. No metal I can see or on the cover magnet. My problem had been a slip and moan sort of noise if excelerating quick from a stop, or going up a steep hill from a stop. Once in motion all seems fine. Changing out the fluid, but I don't know what else to check.

Everything looks ok in the pics (to me), but foamy gear oil isn't good. Clean it out real good with brake cleaner - it's like they put in the wrong stuff or somehow water got in.

Somethings not right with that fluid. It should not be foamy. And just from the pic, it looks "runny".

Just got it all cleaned out and buttoned up. Added valvoline 80-90w dino with the additive. There did seem to be some slop in the pinion gear when I rocked the rear wheels. Didn't have the front off the ground so I wasn't able to spin the driveshaft. Going for a test drive after dinner. Keeping my fingers crossed Thanks all Dennis
