Disassembly and assembly

Differential Overhaul

Disassembly Procedure





1. Remove the differential side bearings.

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

2. Remove the 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.

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





4. Remove the differential pinion gears and the differential side gears by performing the following steps:
4.1. Mark the pinion gears top and bottom and the differential side gears left and right.
4.2. Remove the pinion shaft lock bolt.
4.3. Remove the pinion shaft.
4.4. Roll the differential pinion gears out of the case with the pinion gear thrust washers.
4.5. Remove the differential side gears and the side gear thrust washers.

Assembly Procedure





1. Lubricate the pinion and side gears using axle lubricant. Use the proper fluid.
2. Install the differential side gear thrust washers to the differential side gears.
3. Install the differential side gears and thrust washers into the differential case.
If the same differential side gears and the thrust washers are being used, install the gears and the thrust washers to their original locations.
4. Install the differential pinion gears and pinion gear thrust washers by performing the following steps:
4.1. Position one pinion gear between the differential side gears.
4.2. Position the second pinion gear between the differential side gears directly opposite the of the first gear.
4.3. Rotate the differential side gears until the pinion gears is directly opposite the opening in the differential case.
4.4. Install the thrust washers. Rotate the pinion gears toward the differential opening in order to permit the sliding in of the thrust washers.
5. Install the pinion shaft.
