POWER STEERING (P / S) SYSTEM 3B1-7
STEERING WHEEL
STEERING WHEEL PLAY CHECK
Check steering wheel for looseness or rattle by trying to move it in
its shaft direction and lateral direction.
If found defective, repair or replace.
Check steering wheel for play, holding car in straight forward condi-
tion on the ground and with engine stopped.
Steering wheel play ªaº: 0 ± 30 mm (0 ± 1.2 in.)
If steering wheel play is not within specification, inspect as follows
and replace if found defective.

Tie-rod end ball stud for wear

Lower ball joint for wear

Steering shaft joint for wear

Steering pinion or rack gear for wear or breakage

Each part for looseness
STEERING FORCE CHECK
1) Place vehicle on level road and set steering wheel at straight-
ahead position.
2) Check that tire inflation pressure is as specified. (Refer to tire
placard.)
3) Start engine and keep it running till power steering fluid is
warmed to 50 to 60C (122 to 140F).
4) With engine idling, measure steering force by pulling spring ba-
lancer hooked on steering wheel in tangential direction.
Steering force: Less than 50 N (5.0 kg, 11.0 lb)
POWER STEERING FLUID
POWER STEERING FLUID LEVEL CHECK
With engine stopped, check fluid level indicated on P / S fluid reser-
voir, which should be between ªMAXº and ªMINº marks. If it is lower
than ªMINº mark, fill fluid up to ªMAXº mark.
NOTE:

Be sure to use an specified power steering fluid.

Fluid level should be checked when fluid is cool.

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.

INSTALLATION
Reverse removal procedure to install coil spring.
NOTE:
Upper and lower diameters of coil spring are different.
Bring larger diameter end at bottom and set its open end in
place on spring seat.

Be sure to use specified torque for tightening each fastener.

Refer to torque specification chart at the end of this section.

As for ball stud nut, be sure to insert split pin and bend it after tight-
ening it.

Tighten tie-rod end nut with pushing ball stud to upper side so as
not ball stud to be rotated.
