Tools Required
- J 22536 Pinion Driver
Removal Procedure
1. Raise the vehicle.
2. Remove the tire and wheel assemblies.
3. Remove the brake drums. Refer to Brake Drum Replacement See: Drum Brake System > Procedures.
4. Remove the axle shafts. Refer to Rear Axle Shaft Replacement See: Axle Shaft Assembly > Procedures.
5. Remove the differential. Refer to Differential Replacement See: Differential Assembly > Procedures.
6. Remove the drive pinion flange/yoke and the seal. Refer to Drive Pinion Flange/Yoke and/or Oil Seal Replacement See: Seals and Gaskets, Differential > Procedures.
7. Install the J 22536 as shown.
Ensure that the J 22536 is firmly seated on the pinion.
8. 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.
9. Remove the collapsible spacer from the pinion. Discard the spacer.
10. Remove the pinion bearings and the bearing cups. Refer to Drive Pinion Bearings Replacement See: Pinion Bearing, Differential > Procedures.
11. 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.
12. 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.
1. Install the ring gear to the differential case.
Important: The ring gear bolts have left-hand threads.
2. 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.
3. Tighten 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 8.6 inch axle, tighten the ring gear bolts in sequence to 120 Nm (89 lb ft).
- For the 9.5 inch axle, tighten the ring gear bolts in sequence to 140 Nm (103 lb ft).
4. Install the pinion bearing cups. Refer to Drive Pinion Bearings Replacement See: Pinion Bearing, Differential > Procedures.
5. Determine the selective shim thickness for the pinion gear. Refer to Pinion Depth Adjustment See: Differential Assembly > Procedures.
6. Install the selective shim onto the pinion.
7. Install the inner pinion bearing to the pinion. Refer to Drive Pinion Bearings Replacement See: Pinion Bearing, Differential > Procedures.
8. Install a new collapsible spacer.
9. Lubricate the pinion bearings with axle lubricant. Refer to Fluid and Lubricant Recommendations in Maintenance and Lubrication See: Fluid - Differential > Specifications.
10. Install the pinion to the axle housing.
11. Install the outer pinion bearing. Refer to Drive Pinion Bearings Replacement See: Pinion Bearing, Differential > Procedures.
12. Install a new pinion oil seal and the pinion yoke. Refer to Drive Pinion Flange/Yoke and/or Oil Seal Replacement See: Seals and Gaskets, Differential > Procedures.
13. Install the differential. Refer to Differential Replacement See: Differential Assembly > Procedures.
14. Perform a gear tooth contact pattern check on the pinion and the ring gear. Refer to Gear Tooth Contact Pattern Inspection See: Differential Assembly > Procedures.
15. Install the axle shafts. Refer to Rear Axle Shaft Replacement See: Axle Shaft Assembly > Procedures.
16. Install the brake drums. Refer to Brake Drum Replacement See: Drum Brake System > Procedures.
17. Install the tire and wheel assemblies.
18. Fill the axle with lubricant. Use the proper fluid. Refer to Approximate Fluid Capacities and Fluid and Lubricant Recommendations in Maintenance and Lubrication See: Fluid - Differential > Specifications.
19. Lower the vehicle.
This is for ring and pinion replacement, diff will be pretty much the same
