(10.5 Inch Axle)

Drive Pinion and Ring Gear Replacement (10.5 Inch Axle)

Removal Procedure

1. Raise the vehicle.
2. Remove the differential. Refer to Differential Replacement .
3. Remove the pinion gear bearing retainer. Refer to Drive Pinion Housing and/or Seal Replacement .
4. Remove the pinion and the pinion bearings. Refer to Drive Pinion Housing and/or Seal Replacement .






5. Remove the left handed threaded ring gear bolts. Discard the 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.

6. Remove the ring gear from the differential. Drive the gear off with a brass drift if necessary.

Installation Procedure






1. If the differential case has become separated, assemble the differential case by aligning the two arrows inside 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.

2. Install the ring gear to the differential case.






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

3. Install the new ring gear bolts.

Hand start each bolt to ensure that the ring gear is properly installed 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.

4. Tighten the ring gear bolts. Tighten the ring gear 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).

5. Install the pinion and the pinion bearings. Refer to Drive Pinion Housing and/or Seal Replacement .
6. Install the pinion gear bearing retainer. Refer to Drive Pinion Housing and/or Seal Replacement .
7. Install the differential assembly. Refer to Differential Replacement .
8. Lower the vehicle.
