Inspection After Disassembly of Carrier

IN CARRIER HOUSING
Make sure the differential bearing bores are smooth (if applicable). Remove any nicks or burrs from the mounting surfaces of the rear axle housing.

ON DIFFERENTIAL CASE
^ Make sure the differential bearing bores are smooth. Remove any nicks or burrs from the mounting surfaces of the differential case
^ Make sure that the hubs where the differential bearings mount are smooth. Carefully examine the differential case bearing shoulders which may have been damaged when the differential bearings were removed. The bearing assemblies will fail if they do not seat firmly against the shoulders.
^ Check the fit (free rotation) of the differential side gears in their counterbores. Make sure the mating surfaces of the two parts of the case (if applicable) are smooth and free from nicks or burrs.
