Differential Case: Testing and Inspection
Ensure the hubs where bearings mount are smooth. Check fit of differential gears in the counterbores. Carefully examine thrust washers, which may be
damaged when bearings are removed. If differential bearing assemblies do not seat firmly on hubs, failure is certain. Ensure mating surfaces of the two
parts of case and the face of the ring gear attaching flange are smooth and free from nicks and burrs.
