First, stop driving it. Second, pop the differential cover and have a peek. You're looking for broken ring or pinion teeth, broken teeth in the carreer gears, or metal chunks/flakes/shards in the fluid.

the pinion pin is probably rounding out betwen the helical gears but you will save the ring gear and pinion gear.
