4. Align the lock pin hole on the differential case with the lock pin

hole on the pinion mate shaft, and install the pinion mate shaft.

5. Measure the side gear end play. If necessary, select the appro-

priate side gear thrust washers. Refer to 

DLN-270, "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. Apply thread locking sealant into the threaded holes of the drive

gear and install the bolts.

• Use Genuine Medium Strength Thread Locking Sealant or

equivalent. Refer to 

GI-15, "Recommended Chemical Prod-

ucts and Sealants"

.

CAUTION:

Make sure the drive gear back and threaded holes are

clean.

9. Tighten the drive gear bolts to the specified torque. After tighten-

ing the drive gear bolts to the specified torque, tighten an addi-

tional 34

° using Tool.

CAUTION:

• Always use Tool. Avoid tightening based on visual check

alone.

• Tighten drive gear bolts in a crisscross pattern.

10. Press the side bearing inner races into the differential case

using Tools.

CAUTION:

Do not reuse side bearing inner race.

11. Install the differential case assembly with the side bearing outer

races into the gear carrier.

12. Measure the side bearing preload torque. If necessary, select

the appropriate side bearing adjusting washers. Refer to 

DLN-

270, "Inspection and Adjustment"

.

13. Insert the selected left and right side bearing adjusting washers

in place between the side bearings and gear carrier.

14. Install the side bearing caps with the matching marks aligned

and tighten the side bearing cap bolts to the specified torque.

15. Check and adjust the drive gear runout, tooth contact, drive gear to drive pinion backlash, and total pre-

load torque. 

Recheck the above items.

16. Install the side flanges.

17. Apply a 3.2mm (0.126 in) bead of sealant to the mating surface

of the carrier cover.

• 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-249, "Removal and Installa-

tion"

.

19. Install the side flange. Refer to 

DLN-247, "Removal and Installa-

tion"

.

1. Apply multi-purpose grease to the lips of the new side oil seal.

Then drive the new side oil seal in evenly until it becomes flush

with the gear carrier using 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.

2. Install the side flange using Tool.
a. Install the Tool to the side oil seal as shown.

b. Insert the side flange until the serrated part of the side flange

has engaged the serrated part of the side gear and remove the

Tool.

c. Drive in the side flange using suitable tool.

NOTE:

Installation is completed when the driving sound of the side

flange turns into a sound which seems to affect the whole rear

final drive assembly.
