I've seen rear wheel bearing problems but not rear differential problems. Agree with previous answer get the oil hot drain it into a clean pan, inspect for debris refill with fresh GL5 80/90W

check fluid level in rear differential. When you check it use a clean dipstick or something similiar to pull some fluid out. If you see metal flakes on dipstick the differential could be going, or the fluid could be low and just fill it up.
