5.1.1 TROUBLESHOOTING the DIFFERENTIALS
Differential Service
When symptoms point to differential troubles, remove the differential carrier or rear
inspection cover. Inspect the ring gear, pinion drive gear, bearings, and spider gears.
A differential ID number is provided to show the exact type of differential for ordering
parts and looking up specifications. The number may be on a tag under one of the
carrier or inspection cover fasteners. It may also be stamped on the axle housing or
carrier. Use the ID number to find the axle type, axle ratio, make of unit, and other
information.
Differential Removal
To remove a differential carrier from the banjo housing, use the following procedure:
1. Use a hydraulic jack to raise the vehicle axle housing so that the wheels just
clear the floor.
2. Place axle stands under each side of the axle housing to hold the vehicle in the
raised position. Try to make sure the axle housing is horizontally close to level.
3. Remove the drain plug from the bottom of the axle housing and drain the
lubricant from the assembly. Dispose of the lube properly.
