10.5 Inch Axle
Differential Overhaul (10.5 Inch Axle)^ Tools Required
- J 8092 Driver Handle
- J 29710 Side Bearing Installer
- J 22912-01 Split Plate Bearing Puller
Disassembly Procedure
1. Remove the differential side bearings by performing the following steps:
1.1. Install the J22912-01.
1.2. Remove the differential side bearings using the J 22912-01 and a hydraulic press.
Notice: Do not pry the ring gear from the case. This will damage the ring gear and the differential case.
2. Remove the ring gear bolts.
The ring gear bolts have left-handed threads.
3. Remove the ring gear from the differential case. Drive the ring gear off with a brass drift if necessary.
4. Separate the differential case assembly.
Important: If the differential pinion gears, the differential side and the thrust washers are to be reused, mark the components so they can be re-installed in their original location in the differential case.
5. Remove the following from the differential case:
^ The thrust washers
^ The differential pinion gears
^ The differential pinion spider
6. Remove the differential side gears.
Assembly Procedure
1. Lubricate the differential side gears and the differential pinion gears with axle lubricant. Use the proper fluid.
2. Install the differential side gears into the differential case. If the original differential side gears are being used, install the gears in the original location.
3. Assemble the differential pinion gears and the thrust washers to the differential spider as shown.
If the original differential pinion gears, the thrust washers and the differential spider are being used, install the components in the original locations.
4. Assemble the differential case halves.
Align the arrow in the differential case as shown.
Important: The mating surface of the ring gear and the differential case must be clean and free of burrs before installing the ring gear.
5. Install the ring gear to the differential case.
Notice: Refer to Fastener Notice in Service Precautions.
6. Install the ring gear bolts. Tighten the ring gear bolts alternately and in stages, gradually pulling the ring gear onto the differential case.
^ Tighten the ring gear bolts in sequence to 165 Nm (122 ft. lbs.).
7. Install the differential side bearings by doing the following:
7.1. Install the J29710 and the J8092 onto the differential case bearing.
7.2. Drive the bearing onto the case using the J 29710 and the J 8092.
