4. Install the pinion mate shaft and align the lock pin hole on the
pinion mate shaft with the lock pin hole on the differential case.
5. Measure the side gear end play. If necessary, select the appro-
priate side gear thrust washers. Refer to
6. Drive a new lock pin into the pinion mate shaft until it is flush
with the differential case using suitable tool.
CAUTION:
Do not reuse lock pin.
7. Align the matching mark of the differential case with the mark of
the drive gear, then place the drive gear onto the differential
case.
8. Install and tighten the new drive gear bolts to the specified
DLN-217, "Disassembly and Assembly"
.
CAUTION:
• Make sure the drive gear back and threaded holes are
clean.
• Do not reuse drive gear bolts.
• Tighten new drive gear bolts in a crisscross pattern.

10. Install side bearing adjusters into gear carrier.
11. Apply differential gear oil to the side bearings, and install the dif-
ferential case assembly with the side bearing outer races into
the gear carrier.
CAUTION:
Do not reuse side bearing outer race when replacing side
bearing inner race (replace as a set).
12. Install the side bearing caps with the matching marks aligned.
NOTE:
Do not tighten at this step. This allows further tightening of side
bearing adjusters.
13. Tighten each side bearing adjuster alternately turning drive gear.
14. Check and adjust tooth contact, backlash, drive gear runout and total preload torque.
Recheck above items.
• After adjusting tooth contact and backlash secure side bearing
adjuster with screws and tighten side bearing cap bolt to the
DLN-217, "Disassembly and Assem-
.
15. Apply multi-purpose grease to the lips of the new side oil seal. Then drive the new side oil seal in evenly to
the gear carrier using suitable tool.
CAUTION:
• Do not reuse side oil seal.
• Do not incline the new side oil seal when installing.
• Apply multi-purpose grease to the lips of the new side oil seal.

16. Install the extension tube with a new O-ring.
CAUTION:
• Do not reuse O-ring.
• If the extension tube is being replaced, install a new axle
shaft bearing.
17. Apply 3 mm (0.12 in) bead of sealant to the mating surface of
the carrier cover as shown.
• Use Genuine Silicone RTV or equivalent. Refer to
"Recommended Chemical Products and Sealants"
CAUTION:
Remove any old sealant adhering to the mating surfaces.
Also remove any moisture, oil, or foreign material adhering
to the application and mating surfaces.
18. Install the carrier cover to the gear carrier. Tighten the bolts to
the specified torque. Refer to
DLN-214, "Removal and Installa-
19. Install side shaft and side flange.
