REPAIR PROCEDURE
I. Most repair operations begin with an overview illustration. It identifies the components, shows how the
parts fit together, and visual parts inspections. If a damaged or worn part is found, repair or replace it
as necessary.
2. Expendable parts, tightening torques, and symbols for oil, grease, and sealant are shown in the overview
illustration.
3. Pages related to service procedures are shown under the tllustration. Refer to this informatron when ser-
vicing the related part

FUNDAMENTAL PROCEDURES GI
A WORD ABOUT SAFETY
The following precautions must be followed when jacking up
the vehicle.
t . Block the wheels.
2. Use only the specfred jacking positions.
3. Support the vehicle with safety stands.
Start the engine only after making certain the engine compart-
ment is clear of tools and people. j
9MUGtX-003 PREPARATION OF TOOLS AND MEASURING
EQUIPMENT
8e sure that al! necessary toois and measuring equipment
are available before starting any work.
SPECIAL TOOLS
Use special tools when they are required.
47UOGX-Cm I 1 REMOVAL OF PARTS
While correcting a problem, try also to determine its cause
Begin work only after first learning which parts and subas-
semblies must be removed and disassembled for replace-
ment or repair. >
DISASSEMBLY
If the disassembly procedure is complex, requiring many
parts to be disassembled, all parts should be disassembled
in a.way that wiii not affect their performance or external
appearance and identified so that reassembly can be per-
formed easily and efficiently. I J

GI FUNDAMENTAL PROCEDURES
I. Inspection of parts
When removed, each part should be carefully inspected for
malfunctioning, deformation, damage, and other problems.
2. Arrangement of parts
All disassembled parts should be carefully
arranged for re-
assembly.
Be sure to separate or otherwise identify the parts to be
replaced from those that will be reused.
3. Cteaning parts for reuse
All parts to be reused should be carefully and thoroughly
cleaned in the appropriate method.

9MUGIX-042
REASSEMBtY
Standard values, such as torques and certain adjustments,
must be
strictly observed in the reassembly of all parts.
Refer to STANDARD BOLT AND NUT TIGHTENING TORQUE
in Section TD for tightening torques not mentioned in the main
text.
tf removed, these parts should be replaced with new ones:
1. Oil seals
2, Gaskets
3. O-r.ings
4. Lock washers
.
5. Cotter pins
6. Nylon nuts
Depending on location:
1. Sealant should be applied to gaskets.
2. Oil should be applied
to the moving components of parts.
3. Specified oil or grease should be applied at the prescribed
locations (such as oil seals) before reassembty.

Caution
l Do not clutch abruptly. l Do not attempt rabbit starts or accelerate quickly.
1. Remove the propeller shaft.
2. Lock the center differential (2WD).
3. Place the front wheets on the roller.
4. Lock the rear wheels and apply the parking brake.
5. Drive the tester roller and check.
6. Upon completion of the test, gradually decelerate with soft
braking and stop the engine.
7. When the test is done, return the differential lclck rod to the
free condition (4WD) and reinstall the propeller shaft.
WHEEL BALANCER (On-the-car Balance)
1.
Jack up all four wheels. Support the wheels to be checked
(front or rear) with the wheel balancer sensor stand and the
remainrng wheels with safety stands.
2. Set the on-the-car balancer. With the center differential in
free condition, drove the tires with the engine; then check.
