Differential Case



Ensure that 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 that 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.
