Pinion Bearing: Service and Repair

REMOVAL
1. Disassemble differential/axle housing.
1. Using a press and Pinion Bearing Cone Remover T71P-4621-B. remove differential pinion bearing assembly from the rear axle differential pinion.





2. Remove the drive pinion bearing adjustment shim from the drive pinion.

NOTE: Measure the drive pinion bearing adjustment shim, which is found under the differential pinion bearing, with a micrometer and record the thickness. Use this as a reference to compare the shim gauge reading before installing the bearing.

3. If replacing the differential pinion bearings, tap alternately (with a brass drift of suitable length) on each side of the differential bearing cup during removal to prevent differential bearing cups from cocking in the carrier bore. Remove differential bearing cups.

NOTE: To make sure bearings are properly seated, clean bores before installing differential pinion bearings.





INSTALLATION
