3D-2 FRONT SUSPENSION
GENERAL DESCRIPTION
The front suspension is the strut type independent suspension. The upper end of a strut is anchored to the body
by a strut support. The strut and strut support are isolated by a 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 this steering knuckle
is connected to the tie rod end.
Thus, movement of the steering wheel is transmitted to the tie rod end and then to the knuckle, eventually causing
the wheel-and-tire to move.

SUSPENSION CONTROL ARM JOINT CHECK
1) Check for smoothness of rotation.
2) Inspect ball stud for damage.
3) Inspect dust cover for damage.
Replace any parts found defective in steps 1) ± 3).
SUSPENSION CONTROL ARM BUSHING
CHECK
Inspect for damage, wear or deterioration.
WHEEL DISC, NUT & BEARING CHECK
1) Inspect each wheel disc for dents, distortion and cracks.
Disc in badly damaged condition must be replaced.
2) Check wheel nuts for tightness and retighten them to specifica-
tion as necessary.
Tightening Torque
(a): 100 N
.m (10.0 kg-m, 72.5 lb-ft)
3) Check wheel bearing for wear. After retightening lock nut to spe-
cified torque, apply dial gauge to wheel hub center and measure
thrust play.
Thrust play limit: 0.05 mm (0.002 in.)
When measurement exceeds limit, replace bearing.
4) By rotating wheel actually, check wheel bearing for noise and
smooth rotation. If defective, replace bearing.

REMOVAL
1) Hoist vehicle.
2) Remove stabilizer bar mount bush bracket bolts.
3) Remove stabilizer ball joint nuts, washers and bushings.
4) Remove stabilizer bar with its ball joints.
5) Disconnect stabilizer ball joints from stabilizer bar.
INSTALLATION
NOTE:
For correct installation of stabilizer bar, side-to-side, be sure
that color paint on stabilizer bar aligns with mount bush, both
right and left, as shown.
1) Connect stabilizer ball joints and stabilizer bar.
2) Install stabilizer ball joints to control arms.
NOTE:
Do not tighten stabilizer ball joint nuts completely.
3) Install stabilizer bar mount bush brackets.
4) When installing stabilizer, loosely assemble all components
while insuring that stabilizer is centered, side-to-side.
Check that ball joint is set at neutral position seeing from body
upper side.
5) Tighten stabilizer bracket bolts and stabilizer ball joint nuts to
specified torque.
