10.5 Inch Axle

Differentail Overhaul (10.5 Inch Axle)

Disassembly Procedure

1. Remove the differential side bearings. Refer to Differential Bearing Replacement Side Bearings Replacement.






Important: The ring gear bolts have left-hand threads.

2. Remove the ring gear bolts.

Notice: Do not pry the ring gear from the differential case. Prying the ring gear from the differential case may cause damage to the ring gear and/or the differential case.

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. Refer to Fluid and Lubricant Recommendations .






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: 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.

6. Install the new ring gear bolts.
Hand start each bolt in ensure the ring gear is properly installed to the differential case.
7. Tighten the ring gear bolts. Tighten the bolts alternately and in stages, gradually pulling the ring gear onto the differential case.

Tighten
Tighten the ring gear bolts in sequence to 165 Nm (122 lb ft).

8. Install the differential side bearings. Refer to Differential Bearing Replacement Side Bearings Replacement.
