MAINTENANCE AND LUBRICATION 0B-15
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
Inspect front struts & rear shock absorbers for evidence of oil
leakage, dents or any other damage on sleeves ; and
inspect anchor ends for deterioration.
Replace defective parts, if any.
Check front and rear suspension systems for damaged,
loose or missing parts ; also for parts showing signs of wear
or lack of lubrication.
Repair or replace defective parts, if any.
Check front suspension arm ball joint stud dust seals for
leakage, detachment, tear or any other damage.
Replace defective boot, if any.
STEERING SYSTEM
INSPECTION
1) Check steering wheel for play and rattle, holding vehicle
straight on ground.
Steering wheel play
“a” : 0 – 30 mm (0 – 1.1 in.)
2) Check bolts and nuts for tightness and retighten them as
necessary. Repair or replace defective parts, if any.
3-2 STEERING, SUSPENSION, WHEELS AND TIRES
DIAGNOSIS
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. Pro-
ceed with the following preliminary inspection 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 wheels. Inspect for out-of-round tires, out-of-balance tires, bent rims, loosen and/or rough wheel
bearings.

GENERAL DESCRIPTION
The front suspension is the strut type independent suspension. The upper end of a strut is anchored to the vehi-
cle body by a strut support. The strut and strut support are isolated by a rubber mount. A strut bearing is also
installed a little lower to the rubber mount.
The lower end of the strut is connected to the upper end of a steering knuckle and lower end of knuckle is
attached to the stud of a ball joint which is incorporated in a unit with a suspension control arm. And connected
to this steering knuckle is the tie rod end.
Thus, movement of the steering wheel is transmitted to the tie rod end and then to the knuckle, eventually caus-
ing the wheel-and-tire to move. In this operation, with the movement of the knuckle, the strut also rotates by
means of the strut bearing and lower ball joint.NOTE:
All front suspension fasteners are an important attaching part in that it could affect the perfor-
mance of vital parts and systems, and/or could result in major repair expense. They must be
replaced with one of the same part number or with an equivalent part if replacement becomes nec-
essary. Do not use a replacement part of lesser quality or substitute design. Torque values must be
used as specified during reassembly to assure proper retention of this part.
Never attempt to heat, quench or straighten any front suspension part. Replace it with a new part or
damage to the part may result.
FRONT SUSPENSION 3D-5
FRONT SUSPENSION FASTENERS CHECK
Check each bolt and nut fastening suspension parts for tightness.
Tighten loose one, if any, to specified torque, referring to “GEN-
ERAL DESCRIPTION” in this section.
WHEEL DISC, NUT AND BEARING CHECK
Inspect each wheel disc for dents, distortion and cracks.
A disc in badly damaged condition must be replaced.
Check wheel nuts for tightness and, as necessary, retighten
them to specification.
Tightening torque
Wheel nut (a) : 85 N·m (8.5 kg-m, 61.5 lb-ft)
Check wheel bearing for wear. When measuring thrust play,
apply a dial gauge to wheel hub.
Thrust play limit
: 0.1 mm (0.004 in.)
By rotating wheel actually, check wheel bearing for noise
and smooth rotation.
If defective, replace bearing.
