[FRONT FINAL DRIVE: R180A]

FRONT FINAL DRIVE

Install side gear thrust washers with the same thickness as the
ones installed prior to disassembly, or reinstall the old ones on
the side gears.

Install the side gears and side gear thrust washers into the dif-
ferential case.

Install the pinion mate thrust washers to the two pinion mate
gears. Then install the pinion mate gears with the pinion mate
thrust washers by aligning them in diagonally opposite positions
and rotating them into the differential case.

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.

PRECAUTIONS

Precaution for Servicing Front Final Drive

INFOID:0000000001315882

• 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.
