FRONT FINAL DRIVE

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.

Measure the side gear end play. If necessary, select the appro-
priate side gear thrust washers. Refer to

DLN-364, "Inspection

and Adjustment"

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.

Align the matching mark of the differential case with the mark of
the drive gear, then place the drive gear onto the differential
case.

Install and tighten the new drive gear bolts to the specified
torque. Refer to

DLN-345, "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.

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. Refer to

DLN-364,

"Inspection and Adjustment"

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-345, "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-26,

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-345, "Disassembly and

Assembly"

19. Install side shaft and side flange.

PRECAUTIONS

Precaution for Servicing Rear Final Drive

INFOID:0000000001297284

• Before starting diagnosis of the vehicle, understand the symptoms well. Perform correct and systematic

operations.

• Check for the correct installation status prior to removal or disassembly. When matching marks are required,

be certain they do not interfere with the function of the parts they are applied to.

• Overhaul should be done in a clean work area, a dust proof area is recommended.
• Before disassembly, completely remove sand and mud from the exterior of the unit, preventing them from

entering into the unit during disassembly or assembly.

• Always use shop paper for cleaning the inside of components.
• Avoid using cotton gloves or a shop cloth to prevent the entering of lint.
• Check appearance of the disassembled parts for damage, deformation, and abnormal wear. Replace them

with new ones if necessary.

• Gaskets, seals and O-rings should be replaced any time the unit is disassembled.
• Clean and flush the parts sufficiently and blow them dry.
• Be careful not to damage sliding surfaces and mating surfaces.
• When applying sealant, remove the old sealant from the mating surface; then remove any moisture, oil, and

foreign materials from the application and mating surfaces.

• In principle, tighten nuts or bolts gradually in several steps working diagonally from inside to outside. If a

tightening sequence is specified, observe it.

• During assembly, observe the specified tightening torque.
• Add new differential gear oil, petroleum jelly, or multi-purpose grease, as specified.
