Differential Case Front Disassembly / Assembly
DIFFERENTIAL CASE FRONT DISASSEMBLY / ASSEMBLYDisassembly Note
1. Remove differential case from the front drive axle housing.
2. Remove the ring gear.
1. Remove the eight bolts.
2. Use a drift that will bottom out in the ring gear bolt holes to separate the ring gear from the differential case.
3. Drive out the differential pinion shaft roll pin from the differential case.
4. Remove the differential pinion shaft.
Note:
^ Differential side gears may fall out after removing the differential pinion gears.
5. Rotate the differential pinion gears to the differential case window and remove them and the differential pinion thrust washers.
6. Remove the differential side gears and the differential side gear thrust washers.
7. Assemble Pinion and Carrier Bearing Puller ST 49 UN01 029.
8. Position Pinion and Carrier Bearing Puller ST 49 UN01 029.
Note:
^ The differential bearings must be installed on the same side they were removed from.
9. Use Pinion and Carrier Bearing Puller ST 49 UN01 029 to remove the differential bearing.
^ Repeat the procedure for the other side.
Assembly Note
1. Install the differential bearings.
1 Position the appropriate differential bearing (RH or LH).
2 Use the appropriate press to install the differential bearing.
0 Repeat for the other differential bearing.
2. Position the differential side gear thrust washers on the differential side gears.
^ Use axle lubricant meeting specification API Service GL-5 to lubricate the differential side gear thrust washers and the differential side gear journals.
3. Position the differential side gears.
4. Use axle lubricant meeting specification API Service GL-5 to lubricate the differential pinion thrust washers and the differential pinion gears and assemble.
5. Engage the differential pinion gears between the differential side gears.
6. Rotate the differential pinion gears to align the differential pinion shaft bore.
7. Insert the differential pinion shaft.
8. Install the differential pinion shaft roll pin.
9. Install the ring gear.
1 Position the ring gear and then start two or three ring gear bolts to align the holes in the ring gear and the differential case.
^ Use an appropriate press to install the ring gear.
10. Install the remaining ring gear bolts.
11. Install the differential case into the front drive axle housing.
