Abuse?
Age?
overheat?
road debris?

that is what would concern me first.

Abuse I am sure, these are 69,000lbs axles on a monster of a truck and this thing gets beat up pretty bad. It is often pulling hard out of mud holes with 6 way lockers engaged or in winter locked up climbing hills at high speeds.

Trucks a 06 and I've owned it for a year with no prior history so I am not sure on the age of the diff or seal but it's just the cost of doing business out here.
