When ever I rebuild my diff I ALWAYS replace the little lock nut. What I think happens, is that constant turning, on the small nut wears the nylon very easily. Yea sure it is the same as the wheel lock nuts but these are a lot smaller. Since I started replacing the lock nuts...no problems at all!!!
