Alignment: Service and Repair
NOTICE: For Zero Point Calibration information, please refer to: TSB T-SB-0020-8 (3/25/08).FRONT WHEEL ALIGNMENT ADJUSTMENT
NOTICE: Be sure to perform the zero point calibration of the steering angle, master cylinder pressure, yaw rate and deceleration sensors.
1. MEASURE VEHICLE HEIGHT
a. Measuring points:
A: Ground clearance of the front drive shaft center
B: Ground clearance of the front adjusting cam bolt center
C: Ground clearance of the rear axle shaft center
D: Ground clearance of the rear lower control arm front bolt center
Vehicle Height (Except Air suspension models):
Vehicle Height (Air suspension models):
NOTICE: Before inspecting the wheel alignment, adjust the vehicle height to the specified value.
If the vehicle height is not as specified, try to adjust it by pushing down on or lifting the body.
2. INSTALL CAMBER-CASTER-KINGPIN GAUGE OR POSITION VEHICLE ON WHEEL ALIGNMENT TESTER
a. Follow the specific instructions of the equipment manufacturer.
3. INSPECT CAMBER, CASTER AND STEERING AXIS INCLINATION
Camber:
Caster (Except air suspension models):
Caster (Air suspension models):
Steering Axis Inclination:
Steering Axis Inclination (Continued):
If the steering axis inclination is not within the specified values, after the camber and caster have been correctly adjusted, recheck the steering knuckle and front wheel bearing for looseness.
4. ADJUST CAMBER AND CASTER
a. Loosen the front and/or rear adjusting cam set bolts.
b. Adjust the camber and caster by turning the front and/or rear adjusting cams (See adjustment chart).
HINT: Try to adjust the camber and caster to the center of the specified values.
c. How to read the adjustment chart (Example).
1. Find the applicable wheel alignment standard value for the particular model.
2. Mark the selected standard value on the adjustment chart.
Example:
Camber: 0°08' (0.13°)
Caster: 2°59' (2.98°)
3. Measure the present wheel alignment value with the vehicle unloaded.
4. Mark the measured present value on the adjustment chart.
Example:
Camber: 0°20' (0.33°)
Caster: 2°59' (2.98°)
5. As shown in the example chart, read the distance from the measured value to the standard value, and adjust the front and/or rear adjusting cams accordingly
Amount to turn the adjusting cams (by graduation):
Example
Front cam: 1.4 (+ direction)
Rear cam: 1.3 (+ direction)
d. Torque the front and/or rear adjusting cam set bolts.
Torque: 130 Nm (1,325 kgf-cm, 96 ft. lbs.)
5. INSPECT TOE-IN
Toe-in (total):
Toe-in (total) (continued):
(*1): Air suspension models only
If the toe-in is not within the specified values, adjust the rack ends.
6. ADJUST TOE-IN AND WHEEL ANGLE
a. Remove the 2 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 values.
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 inch) or less
e. Tighten the tie rod end lock nuts.
Torque: 55 Nm (560 kgf-cm, 41 ft. lbs.)
f. Place the boots on the seats and install the clips.
HINT: Make sure that the boots are not twisted.
g. Inspect the wheel angle.
1. Turn the steering wheel fully and measure the turning angle.
Wheel Turning Angle:
If the right and left wheel turning angles differ from the specified values, readjust the toe-in and wheel angle to within the specified values. At this time, make sure that the lengths of the right and left rack ends are the same.
Rack end length difference: 1.5 mm (0.059 inch) or less
