Component Name

Notice: After cleaning the transmission components, allow to air dry. Do not use cloth or paper towels in order to dry any transmission components. Lint from the towels can cause component failure.

Notice: Do not reuse cleaning solvents. Previously used solvents may deposit sediment which may damage the component.

Notice: Keep thrust washers with the gear it was matched to. The thrust washers are selective sizes and it is difficult to identify the proper washer thickness. Improper assembly can cause premature failure of the differential assembly.

Preliminary Procedures

    • Clean and inspect the differential assembly, pinion gears and thrust washers for scoring, wear or damage.
    • The differential assembly is only serviced as an assembly.
