There's also a quick way of checking without pulling the plate, but in the end I always pull the plate to make sure the ring and pinion are in good shape.
Jack the rearend up, mark the driveshaft, and mark the tire. Count how many times the driveshaft turns for 1 revolution of the tire. Less than 3 1/2 times = 3.36, more than 3 1/2 times = 3.61 or 3.70, More than 4 times = 4.11.
