.
- Install the J 22536
as shown.
Ensure that the J 22536
is firmly seated on the pinion.
- Drive the pinion out using the J 22536
and a hammer.
Strike the J 22536
slowly. Do not let the pinion fall out of the rear axle housing.
- Remove the collapsible
spacer from the pinion. Discard the spacer.
- Remove the pinion bearings and the cups. Refer to

.
- Remove the left handed threaded ring gear bolts. Discard the bolts.
- Remove the ring gear from the differential. Drive the gear off
with a brass drift if necessary.
Installation Procedure
Important: The mating surface of the ring gear and the differential case must be
clean and free of burrs before installing the ring gear.
- Install the ring gear
to the differential case.
- Install two threaded studs into the ring gear on opposite sides.
- Place the ring gear on the case. Align the studs with the holes
in the case.
Notice: Use the correct fastener in the correct location. Replacement fasteners
must be the correct part number for that application. Fasteners requiring
replacement or fasteners requiring the use of thread locking compound or sealant
are identified in the service procedure. Do not use paints, lubricants, or
corrosion inhibitors on fasteners or fastener joint surfaces unless specified.
These coatings affect fastener torque and joint clamping force and may damage
the fastener. Use the correct tightening sequence and specifications when
installing fasteners in order to avoid damage to parts and systems.
- Install the new
ring gear bolts. Tighten the ring gear bolts alternately and in stages, gradually
pulling the ring gear onto the differential case.
Tighten
• | For the 7.6 inch axle, tighten the ring gear bolts in sequence
to 100 N·m (74 lb ft). |
• | For the 8.6 inch axle, tighten the ring gear bolts in sequence
to 120 N·m (89 lb ft). |
