lBefore starting diagnosis of the vehicle, understand the symptoms well. Perform correct and systematic
operations.
lCheck 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.
lOverhaul should be done in a clean work area, a dust proof area is recommended.
lBefore disassembly, completely remove sand and mud from the exterior of the unit, preventing them from
entering into the unit during disassembly or assembly.
lAlways use shop paper for cleaning the inside of components.
lAvoid using cotton gloves or a shop cloth to prevent the entering of lint.
lCheck appearance of the disassembled parts for damage, deformation, and unusual wear. Replace them
with new ones if necessary.
lGaskets, seals and O-rings should be replaced any time the unit is disassembled.
lClean and flush the parts sufficiently and blow them dry.
lBe careful not to damage sliding surfaces and mating surfaces.
lWhen applying sealant, remove the old sealant from the mating surface; then remove any moisture, oil,
and foreign materials from the application and mating surfaces.
lIn principle, tighten bolts or nuts gradually in several steps working diagonally from inside to outside. If a
tightening sequence is specified, observe it.
lDuring assembly, observe the specified tightening torque.
lAdd new differential gear oil, petroleum jelly, or multi-purpose grease, as specified.

CAUTION:
Verify identification stamp of replacement frequency put in the lower part of gear carrier to determine
replacement for collapsible spacer when replacing front oil seal. Refer toFFD-9, "
IDENTIFICATION
STAMP OF REPLACEMENT FREQUENCY OF FRONT OIL SEAL". If necessary collapsible spacer
replacement, remove final drive assembly and disassemble it to replace front oil seal and collapsible
spacer. Refer toFFD-15, "
Removal and Installation"andFFD-17, "Disassembly and Assembly".
NOTE:
The reuse of collapsible spacer is prohibited in principle. However, it is reusable on a one-time basis
only in cases when replacing front oil seal.
IDENTIFICATION STAMP OF REPLACEMENT FREQUENCY OF FRONT OIL SEAL
lThe diagonally shaded area in the figure shows stamping point
for replacement frequency of front oil seal.
lThe following table shows if collapsible spacer replacement is
needed before replacing front oil seal.
When collapsible spacer replacement is required, disassemble
final drive assembly to replace collapsible spacer and front oil
seal. Refer toFFD-17, "
Disassembly and Assembly".
CAUTION:
Be sure to make a stamping after replacing front oil seal.
lAfter replacing front oil seal, make a stamping on the stamping point in accordance with the table below in
order to identify replacement frequency.
CAUTION:
Stamping shall be made from left to right.
REMOVAL
1. Drain gear oil. Refer toFFD-8, "DRAINING".
2. Make a judgment if a collapsible spacer replacement is required. Refer toFFD-9, "
IDENTIFICATION
STAMP OF REPLACEMENT FREQUENCY OF FRONT OIL SEAL".
3. Remove the front wheels and tires using power tool.
4. Without disassembling the hydraulic lines, remove the caliper torque member bolts using power tool.
Then reposition the brake caliper aside using suitable wire. Refer toBR-26, "
Removal and Installation of
