Negative Camber
The front suspension adopts negative camber to reduce the ground contact camber angle of the outer wheel
at the time of turning (cornering), which is caused when the vehicle posture changes during cornering, thus
realizing excellent cornering performance.
Suspension Upper Support and Dust Cover
The upper support optimizes the characteris-
tics of the rubber mount. Also, a rebound stop-
per has been provided to ensure riding com-
fort, drivability, and stability.
A bound stopper made of urethane has been
adopted. By optimizing the stopper character-
istics and the clearance, excellent riding com-
fort and a high level of roll rigidity have been
achieved.
An upper insulator that is integrated with the
dust boot has been adopted.

INSPECTION
1. INSPECT STEERING LINKAGE
(a) Check the steering wheel freeplay. (See page SR±3)
(b) Check the steering linkage for looseness or damage.
Check that:

Tie rod ends do not have excessive play.

Dust seals and boots are not damaged.

Boot clamps are not loose.
2. INSPECT SRS AIRBAG (See page RS±2)
3. INSPECT STEERING GEAR HOUSING OIL
Check the steering gear housing for oil leakage.
4. INSPECT DRIVE SHAFT BOOTS
Check the drive shaft boots for clamp looseness, leakage or
damage.
5. INSPECT BALL JOINTS AND DUST COVERS
(a) Inspect the ball joints for excessive looseness.

Jack up the front of the vehicle and place wooden
blocks with a height of 180 ± 200 mm (7.09 ± 7.87
in.) under the front tires.

Lower the jack until there is about half a load on the
front coil spring. Place stands under the vehicle for
safety.

Check that the front wheels are pointing straight
ahead, and block them with chocks.

Using a lever, pry up the end of the lower arm, and
check the amount of play.
Maximum ball joint vertical play: 0 mm (0 in.)
If there is play, replace the ball joint.
(b) Check the dust cover for damage.
6. CHECK TRANSAXLE OIL (FLUID)
Visually check the transaxle for oil (fluid) leakage.
If leakage is found, check for the cause and repair.
7. REPLACE TRANSAXLE OIL (FLUID)
Replace the transaxle oil (See page HT±26).

5. INSPECT TOE±IN
Toe±in:
Toe±in
(total)A + B: 0°06' ± 12' (0.1° ± 0.2°)
C ± D: 1 ± 2 mm (0.04 ± 0.08 in.)
If the toe±in is not within the specified value, adjust it at the rack
ends.
6. ADJUST TOE±IN
(a) Remove the rack boot set clips.
(b) Loosen the tie rod end lock nuts.
(c) Turn the right and left rack ends by an equal amount to
adjust the toe±in.
HINT:
Try to adjust the toe±in to the center of the specified value.
(d) Make sure that the lengths of the right and left rack ends
are the same.
Rack end length difference: 1.5 mm (0.059 in.) or less
(e) Torque the tie rod end lock nuts.
Torque: 74 N´m (750 kgf´cm, 55 ft´lbf)
(f) Place the boots on the seats and install the clips.
HINT:
Make sure that the boots are not twisted.
7. INSPECT WHEEL ANGLE
Turn the steering wheel fully and measure the turning angle.
Wheel turning angle:
Inside wheel42°42' ± 2°
(42.70° ± 2°)
Outside wheel: Reference35°54' (35.90°)
If the right and left inside wheel angles differ from the specified
value, check the right and left rack end lengths.
