FRONT SUSPENSION ASSEMBLY

On-Vehicle Inspection and ServiceEES00072
LOOSENESS, BACKLASH AND DAMAGE OF MOUNTING PARTS AND CONNECTIONS
Lift vehicle and inspect the following:

Check mounting point of each component for looseness, backlash and damage.

Check lower ball joint end play.
1. Attach a dial gauge so that the contact rests on the brake caliper.
2. Set front wheels in a straight-ahead position. Do not depress brake pedal.
3. Measure axial end play by placing an iron pry bar or something similar between transverse link and steer-
ing knuckle.
CAUTION:
Be careful not to damage ball joint boot.
4. If axial end play is outside the standard, remove transverse link and check lower ball joint.
Wheel AlignmentEES00073
DESCRIPTION

Measure wheel alignment under unladen conditions. “Unladen conditions” means that fuel, coolant, and
lubricant are full. However, spare tyre, jack, and hand tools should be unloaded.
PRELIMINARY INSPECTION
1. Check the tyre for improper air pressure and wear.
2. Check road wheels for runout.
3. Check wheel bearing axial endplay.
4. Check lower ball joint axial endplay.
5. Check strut operation.
6. Check each mounting point of axle and suspension for looseness and deformation.
7. Check each link and arm for cracks, deformation, and other damage.
8. Check the vehicle posture.
INSPECTION OF CAMBER, CASTER, AND KINGPIN INCLINATION ANGLES

Camber, caster, and kingpin inclination angles cannot be adjusted.

Before inspection, mount front wheels onto turning radius gauge. Mount rear wheels onto a stand that has
same height so the vehicle will remain horizontal.
1. Measure camber, caster and kingpin inclination of both right and
left wheels with a suitable alignment gauge.
2. If camber, caster or kingpin inclination is not within specification,
inspect front suspension parts. Replace dam-aged or worn out
parts.

2. Check road wheels for runout.
3. Check wheel bearing axial endplay.
4. Check strut operation.
5. Check each mounting point of axle and suspension for looseness and deformation.
6. Check each link and arm for cracks, deformation, and other damage.
7. Check the vehicle posture.
CAMBER
Camber is preset at factory and cannot be adjusted.

If the camber is not within specification, inspect and replace any damaged or worn rear suspension parts.
TOE-IN
Measure toe-in using the following procedure.

Always perform following procedure on a flat surface.

Make sure that no person is in front of the vehicle before push-
ing it.
1. Bounce rear of vehicle up and down to stabilize the posture.
2. Push the vehicle straight ahead about 5 m (16 ft).
3. Put a mark on base line of tread (rear side) of both tyre at the
same height as hub center. This mark is a measuring points.

two balance weight sheets in line with each other (as shown in
the figure).
CAUTION:
Do not install one balance weight sheet on top of another.
3. Start wheel balancer again.
4. Install drive-in balance weight on inner side of road wheel in the
wheel balancer indication position (angle).
CAUTION:
Do not install more than two balance weights.
5. Start wheel balancer. Make sure that inner and outer residual
unbalance values are 10 g (0.35 oz) each or below.

If either residual unbalance value exceeds 10 g (0.35 oz), repeat installation procedures.

RotationEES000J3

After rotating the tyres, adjust the tyre pressure.

Retighten the wheel nuts when the vehicle has been driven for
1,000 km (600 miles) (also in cases of a flat tyre, etc.).
CAUTION:
When installing wheels, tighten the wheel nuts diagonally
by dividing the work two to three times in order to prevent
the wheels from developing any distortion.

CAUTION:
Do not check between wheel sensor terminals.
1. CHECK TYRE
Check air pressure, wear and size.
Are air pressure, wear and size within standard?
YES >> GO TO 2.
NO >> Adjust air pressure, or replace tyre.
2. CHECK SENSOR AND SENSOR ROTOR

Check sensor and sensor rotor.

Check sensor rotor rubber for damage.

Check sensor for disconnection or looseness.
OK or NG
OK >> GO TO 3.
NG >> Repair sensor mount or replace sensor rotor.
3. CHECK SELF-DIAGNOSIS RESULTS
Check the self-diagnostic results.
Is above displayed on self-diagnosis displayed?
YES >> GO TO 4.
NO >> INSPECTION END
4. CHECK CONNECTOR
1. Turn ignition switch OFF, disconnect connector between ABS actuator and electric unit (control unit) and
malfunctioning wheel sensor, and check for deformation, disconnection and looseness. Repair or replace
if necessary.
