rear end fluid change 861

So I changed all the fluids and I had some gold looking glitter in the rear end fluid. I assume something bronze is wearing. What should I be looking at? What could be the problem?

Biggest problem I see is that no one knows what model tractor you're looking at.

I guess that would be helpful. The heat is getting to me today at work. Ford 861 is the tractor

Brass thrust washers between the side gears and the diff case and or pinion gears and the diff case . Somebody probably had some cheap no name hydraulic oil in there with no additives rather the correct 80w90 gear oil like is supposed to be in there same as your 4 and 5 speed transmissions .
