I'm not an expert on these rears, but my first thought is that you need to make sure it has the right gear lube and additive in it.

Are you sure its the right stuff? If not that's the first thing I would look at.

Second thought is that those clutch plates are a wear item and the amount of trouble rebuilding a rear represents, I'd think it would make more sense to look hard for new parts first.

It's true. I really don't do anything but browse the Internet looking for trouble...
