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 

DLN-234, "Inspection

and Adjustment"

.

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

torque. Refer to 

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.

9. Press the new side bearing inner races to the differential case

using Tools.

CAUTION:

Do not reuse side bearing inner races.

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

specified torque. Refer to 

DLN-217, "Disassembly and Assem-

bly"

.

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 

GI-15,

"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-

tion"

.

19. Install side shaft and side flange.
