Lately I have noticed that my rear tires have worn down very fast. It's not from burnouts because I don't do those. Both tires have worn evenly and across all the tread. Everything seems normal except for the fact that they are about 10-15 thousand miles premature. I was wondering, is it possible for the differential to freeze, or nearly completely freeze, to the point that the wheels would basically be sharing a common axle? Yesterday I noticed my LSD was leaking fluid, and quite a bit it would seem. Can a differential freeze up? It doesn't seem likely, but it seems like a logical explaination for the tire wear.
