Ben I didn't realize it was a g80 I'm pretty confident that's your issue. It makes even more sense now. You said diff oil was clean. No chunks of anything or really shiny. That's signature gov bomb. They have some idiotically small bits that can screw stuff up. But will not escape the pretty much enclosed carrier
Diff oil was kind of semi metalic, I'll pull the magnet and take a pic. It wasn't bad but not fantastic.
Step mom's avalanche got in a wreck, nothing bad but found out today they are totalling it...
