When Using Floor Jack
In raising front or rear vehicle end off the floor by jacking, be sure
to put the jack against the center portion of the front axle housing
(1) or rear axle housing (2).
To perform service with either front or rear vehicle end jacked up,
be sure to place safety stands (1) under chassis frame so that
body is securely supported. And then check to ensure that chas-
sis frame does not slide on safety stands (1) and the vehicle is
held stable for safety’s sake. WARNING:
If the vehicle to be jacked up only at the front or rear end,
be sure to block the wheels on ground in order to ensure
safety.
After the vehicle is jacked up, be sure to support it on
stands. It is extremely dangerous to do any work on the
vehicle raised on jack alone.
CAUTION:
Never apply jack against suspension parts (i.e., stabi-
lizer, etc.) or vehicle floor, or it may get deformed.

3) Rotate tires.
For details, refer to “Tire Rotation” in Section 3F.
WHEEL DISCS INSPECTION
Inspect each wheel disc for dents, distortion and cracks. A disc in
badly damaged condition must be replaced.
WHEEL BEARING INSPECTION
1) Check front wheel bearing for wear, damage, abnormal
noise or rattles. For details, refer to “Wheel Disc, Nut and
Bearing Check” in Section 3D.
2) Check rear wheel bearing for wear, damage, abnormal noise
or rattles. For details, refer to “Wheel Disc, Nut and Bearing
Check” in Section 3E.
Suspension System
INSPECTION
Check suspension bolts and nuts for tightness and retighten them
as necessary.
Repair or replace defective parts, if any.
FRONT
1) Check stabilizer bar (6) for damage or deformation.
2) Check bushing (8) for damage, wear or deterioration.
3) Check coil spring (1), lateral rod (5) and leading arm (3) for
deformation and damage.
4) Check lateral rod (5) and leading arm bushings for wear,
damage and deterioration.
5) Inspect absorbers (2) for evidence of oil leakage, dents or
any other damage on sleeves; and inspect anchor ends for
deterioration.
6) Inspect for cracks or deformation in spring seat.
7) Inspect for deterioration of bump stopper.NOTE:
For details of check points, refer to tables of “Tightening
Torque Specification” in Section 3D and 3E.

REAR
1) Check shock absorber (1) for damage, deformation, oil leak-
age and operation.
2) Check bushings for wear and damage.
3) Check coil spring (4), trailing arm (6) and lateral rod (5) for
deformation and damage.
4) Check trailing arm (6) and lateral rod bushings and bump
stopper (2) for wear, damage and deterioration.
5) Check other suspension parts for damage, loose or missing
parts; also for parts showing signs of wear or lack of lubrica-
tion.
Replace any parts found defective in steps 1) to 5).
Propeller Shafts
INSPECTION
1) Check universal joint and spline of propeller shaft for rattle. If
rattle is found, replace defective part with a new one.
2) Check propeller shaft (front & rear) flange yoke bolts for
tightness, and retighten them as necessary.
Refer to “Components” in Section 4B for tightening torque.
LUBRICATION
Grease splines of propeller shaft No.2 (1) and No.3 (2).

General Diagnosis
Since the problems in steering, suspension, wheels and tires involve several systems, they must all be consid-
ered when diagnosing a complaint. To avoid using the wrong symptom, always road test the vehicle first.
Proceed with the following preliminary inspections and correct any defects which are found.
1) Inspect tires for proper pressure and uneven wear.
2) Raise vehicle on a hoist and inspect front and rear suspension and steering system for loose or damaged
parts.
3) Spin front wheel. Inspect for out-of-round tires, out-of-balance tires, bent rims, loose and/or rough wheel
bearings.
