Overhaul

Differential Overhaul

Disassemble Procedure

1. Remove the differential side bearings. Refer to Differential Bearing Replacement (Differential Bearing Replacement).
2. Remove the differential ring gear. Refer to Drive Pinion and Ring Gear Replacement Drive Pinion and Ring Gear Replacement.




3. Separate the differential case (1).





Note: If the differential pinion gears, the differential side and the thrust washers are going to be reused, mark the components so they can be re-installed in their original location in the differential case.

4. Remove the pinion gears (2), thrust washers (1) and the differential spider (3) from the differential case (6).
5. Remove the differential side gears (4) and the thrust washers (5) from the differential case (5).

Assemble Procedure

1. Apply a small amount of the proper gear lubricant to the differential side gears and the differential pinion gears. Refer to Fluid and Lubricant Recommendations (Maintenance).





Note: If reusing the differential side and pinion gears, install them in the original position.

2. Install the thrust washers (5) differential side gears (4) into the differential case (6).
3. Install the differential pinion gears (2), thrust washer (1) on the differential spider (3).
4. Position the differential thrust washers (1), pinion gears (2) and the spider (3) in the differential case (5).




5. Align the arrows on the differential case halves.




6. Position the differential side gear (3) and the thrust washer (3) on the differential pinion gears (4).
7. Install the differential case half (1).
8. Install the differential ring gear. Refer to Drive Pinion and Ring Gear Replacement Drive Pinion and Ring Gear Replacement.
9. Install the differential side bearings. Refer to Differential Bearing Replacement (Differential Bearing Replacement).
