the bearings. Discard the bearings that were removed.
1. Clean all the differential components.
2. Inspect all the differential gears carefully looking for chipped teeth, wear,
or other damage. Because gear tooth damage is rarely isolated to 1 gear,

3. Inspect the gear pins (item 5 in
4. Replace all the differential assembly components that are worn or damaged.
1. If the ball bearing was removed from either cover or housing, press new

5. After the housing is installed, use 1 of the spur gears (refer to

rotate freely without binding. If there is any binding, identify and correct the
cause before securing the cover.
6. Secure the cover to the housing with the 6 socket-head screws; torque the
screws to 11.2 to 13.6 N∙m (99 to 121 in-lb).
