FRONT WHEEL ALIGNMENT
INSPECTION
NOTICE:
w/ VSC:
Be sure to perform the steering angle sensor zero point cal-
ibration after adjusting the front wheel alignment (See page
DI-252).
1. MEASURE VEHICLE HEIGHT
Vehicle height:
Front*1 mm (in.)Rear*2 mm (in.)
213 (8.39)266 (10.47)
*1: Front measuring point
Measure the distance from the ground to the center of the front
side lower suspension arm mounting bolt.
*
2: Rear measuring point
Measure the distance from the ground to the center of the front
side strut rod mounting bolt.
NOTICE:
Before inspecting the wheel alignment, adjust the vehicle
height to the specified value.
If the vehicle height is not the specified value, try to adjust it by
pushing down on or lifting the body.
2. INSTALL CAMBER-CASTER-KINGPIN GAUGE OR
POSITION VEHICLE ON WHEEL ALIGNMENT TES-
TER
Follow the specific instructions of the equipment manufacturer.
3. INSPECT CAMBER, CASTER AND STEERING AXIS
INCLINATION
Camber, caster and steering axis inclination:
Camber
Right-left error-0°37' ± 45' (-0.62° ± 0.75°)
45' (0.75°) or less
Caster
Right-left error2°10' ± 45' (2.17° ± 0.75°)
45' (0.75°) or less
Steering axis inclination
Right-left error13°04' ± 45' (13.07° ± 0.75°)
45' (0.75°) or less
If the caster and steering axis inclination are not within the spe-
cified values, after the camber has been correctly adjusted, re-
check the suspension parts for damaged and/or worn out parts.

5. INSPECT TOE-IN
Toe-in:
Toe-in
(total)A + B: 0° ± 12' (0° ± 0.2°)
C - D: 0 ± 2 mm (0 ± 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, 54 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 wheel35°45' ± 1° (35.75° ± 1°)
Outside wheel: Reference31°23' (31.38°)
If the right and left inside wheel angles differ from the specified
value, check the right and left rack end lengths.

4. CHECK WHEEL BEARING LOOSENESS
(a) Check the backlash in the bearing shaft direction.
Maximum: 0.05 mm (0.0020 in.)
(b) Check the axle hub deviation.
Maximum: 0.05 mm (0.0020 in.)
5. CHECK FRONT SUSPENSION FOR LOOSENESS
6. CHECK STEERING LINKAGE FOR LOOSENESS
7. CHECK BALL JOINT FOR LOOSENESS
8. CHECK SHOCK ABSORBER WORKS PROPERLY

Check that oil leaks

Check mounting bushings for wear

Bounce front and rear of the vehicle
