Inspection After Disassembly of Carrier

- Make sure the differential bearing bores are smooth (if applicable). Remove any nicks or burrs from the mounting surfaces of the differential case.
- Make sure the hubs where the differential bearings mount are smooth.
- Carefully examine the differential 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.
