- 1.
Remove the differential carrier. For additional information, refer to Differential Carrier .
- 2.
Remove and discard the 10 bolts. Remove the ring gear.
NOTE:
Use a drift punch to separate the ring gear from the differential case.
- 3.
Install the differential case with the bearing cups and all the shims in the housing.- 1.
Position the differential case with the bearing cups and shims in their original location.
- 2.
Install the 2 bearing caps.
- 3.
Install the 4 bolts.- Tighten to 105 Nm (77 lb-ft).
- 4.
Rotate the differential case to make sure the bearings have seated correctly.
- 1.
NOTE:
It may be necessary to use the Differential Carrier Spreader to carry out this step.
NOTE:
Visually inspect the differential bearing cups and cones for discoloration indicating bearing overheating or failure.
- 5.
Rotate the differential case and check the differential case runout using the Dial Indicator Gauge with Holding Fixture.- If the runout does not exceed the specification, install a new ring gear and pinion.
- If runout exceeds the specification, the ring gear is true and the condition is due to differential case/differential bearing damage.
- Inspect the differential bearings and the differential case. Always install new differential bearings when installing a new differential case, or if a bearing condition is questionable.
- 6.
Remove the bearing caps and the differential case with the bearing cups and shims from the housing.
- 8.
Install the new differential bearings.- 1.
Position the appropriate differential bearing (RH or LH).
- 2.
Using a suitable press and the Differential Side Bearing Installer, install the differential bearing.- Repeat the steps for the other differential bearing.
- 1.
NOTE:
Press against the differential bearing inner cone only or damage to the component may occur.
- 9.
Install the differential case with the bearing cups and the shims in the housing.- 1.
Position the differential case with the bearing cups and shims in their original locations.
- 2.
Install the 2 bearing caps.
- 3.
Install the 4 bolts.- Tighten to 105 Nm (77 lb-ft).
- 4.
Rotate the differential case to make sure the bearings have seated correctly.
- 1.
NOTE:
Recheck the flange runout.
NOTE:
It may be necessary to use the Differential Carrier Spreader to carry out this step.
- 11.
Using the Dial Indicator Gauge with Holding Fixture, check the runout with the new differential bearings. If the runout does not exceed the specification, use the new differential bearings for assembly.
NOTE:
If the runout is still excessive, install a new differential case.
- 13.
Remove the differential case with the bearing cups and the shims from the housing.- 1.
Remove the 2 bearing caps.
- 2.
Remove the differential case with the bearing cups and the shims from the housing.
- 1.
- 14.
Install the differential ring gear.- 1.
Place the differential ring gear on the differential assembly.
- 2.
Hand-start 3 new ring gear bolts to align the holes in the differential ring gear and the differential assembly.
- 3.
Place the differential carrier and differential ring gear onto the press bed blocks with the differential ring gear teeth facing downward.
- 4.
Press the differential ring gear into place.
- 1.
- 16.
Install the differential carrier. For additional information, refer to Differential Carrier .
