First, look at the inside of your rear wheels, and at the front of the differential, there will be signs of oil, no other way for it to get out. Unless not filled at the factory (this does ocasionally happen)

As long as the gear can reach some oil, it will throw it around enough to keep rear end quiet.

So can be pretty low and not cause a bad problem, although wear is increased.

At this point, rear end needs rebuilt, the gears will also normally be damaged, since few mechanics can actually set up a rear end correctly, I say find a good rear end in a wrecking yard, same ratio, and have it installed with fresh synthetic oil and new brakes, axle seals and if the axel was removed for any length of time, put in new wheel cylinders also. If there is any evidece of pinion leak, then have new pinion seal installed, but if not leaking, leave it alone, some mechanics will not follow the rules for these and mess up the rear end.

Sorry about your troubles. Another reason why I change all my own fluids. Besides being cheap!
