MAINTENANCE AND LUBRICATION 0B-21
Change
1) Inspect transmission case for evidence of fluid leakage.
Repair leaky point, if any.
2) Make sure that vehicle is placed level for fluid level check.
3) Change fluid. For its procedure, refer to On-vehicle service in
Section 7B1.
Fluid cooler hose change
Replace inlet and outlet hoses of cooler hose and their clamps.
For replacement procedure, refer to On-vehicle service in Section
7B1.

Transfer and Differential Oil Inspection and Change
Inspection
1) Check transfer case and differential for evidence of oil leakage.
Repair leaky point if any.
2) Make sure that vehicle is placed level for oil level check.
3) Remove level plug of transfer or differentials (front and rear) and
check oil level.
Oil level can be checked roughly by means of level plug hole.
That is, if oil flows out of level plug hole or if oil level is found up
to hole when level plug is removed, oil is properly filled.
If oil is found insufficient, pour specified amount of specified oil
referring to Section 7D, 7B or 7F.
4) Tighten level plug to specified torque.
Refer to Section 7D, 7E or 7F for tightening torque.
Change
Change transfer oil or differentials oil with new specified oil referring
to Section 7D, 7E and 7F respectively.

7D-2 TRANSFER
DIAGNOSIS
DIAGNOSIS TABLE
Before attempting to repair the transfer or related components for any reason other than mechanical failure, the
condition and probable causes should be identified.
Transfer failures are revealed by shifting difficulties such as excessive shifting effort, gear clash, or gear grinding.
When any of these conditions occur, the following inspections should be made before disassembling the transfer.
1) Check transfer oil level for insufficient or incorrect oil. Refer to ªTransfer and Differential Oil Inspection and
Changeº in SECTION 0B ªMAINTENANCE AND LUBRICATIONº.
2) Check transfer mountings for wear or looseness.
3) Check gearshift control lever for distortion or excessive wear.
After performing the above inspections, refer to following diagnosis table.

7E
DIFFERENTIAL (FRONT) 7E-1
The differential assembly using a hypoid bevel pinion
and gear is installed to the front axle.
4WD control system controls drive force to be trans-
mitted to front axles or not. The reduction ratio varies
depending on transmission or engine type.The differential assembly is decisive in that the drive
power is concentrated there. Therefore, use of genu-
ine parts and specified torque is compulsory. Further,
because of sliding tooth meshing with high pressure
between bevel pinion and gear, it is mandatory to lu-
bricate them by hypoid gear oil.

ON-VEHICLE SERVICE
MAINTENANCE SERVICE
NOTE:

When having driven through water, check immediately if wa-
ter has entered (if so, oil is cloudy). Water mixed oil must be
changed at once.

Whenever vehicle is hoisted for any other service work than
oil change, also be sure to check for oil leakage and status
of breather hoses.
Gear Oil Change
NOTE:

Hypoid gear oil must be used for differential.

It is highly recommended to use SAE 80W ± 90 viscosity.
1) Before oil change or inspection, be sure to stop engine and lift
up vehicle horizontally.
2) Check oil level and existence of leakage. If leakage is found, cor-
rect its cause.
3) Drain old oil and pour proper amount of gear oil as specified be-
low (roughly up to level hole).
4) Apply sealant to thread of drain plug (b) and torque plugs to
specification.
