Usually that means you have filled the rear pumpkin with water. The
gear oil floats on top and presses at the back of the seals so it leaks
out and gets spun away by the tires. Your brake shoes are now likely
garbage too.

Is the high water vent on the rear axle clear and hooked up? Have you
crossed any water lately?

It is time to check the rear end fluid anyway. If it pours out the
hole, then you have water likely. The water raises the oil level. If
it looks like a purple milkshake, you have water for sure.
