Alignment: Service and Repair
FRONT WHEEL ALIGNMENTADJUSTMENT
Standard Vehicle Height:
1. INSPECT VEHICLE HEIGHT
Standard Vehicle Height:
Measuring points:
A: Ground clearance of spindle center
B: Ground clearance of lower suspension arm front bolt center
C: Ground clearance of rear axle shaft center
D: Ground clearance of lower control arm front bolt center
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 TESTER
a. Follow the specific instructions of the equipment manufacturer.
3. INSPECT CAMBER, CASTER AND STEERING AXIS INCLINATION
Standard Camber, Caster And Steering Axis Inclination:
If the steering axis inclination is not within the specified value, after the camber and caster have been correctly adjusted, recheck the steering knuckle and front wheel for wearing or looseness.
Toe-in:
4. INSPECT TOE-IN
Toe-in (total):
A + B: 0°00' ± 12' (0° ± 0.2°)
C - D: 0 ± 2 mm (0 ± 0.08 inch)
If the toe-in is not within the specification, adjust the rack ends.
5. ADJUST CAMBER AND CASTER
NOTICE: After the camber has been adjusted, inspect the toe-in.
a. Loosen the front and/or rear adjusting cam nuts.
b. Adjust the camber and caster using front and/or rear adjusting cams.
HINT: Try to adjust the camber and caster to the center of the specified value.
c. How to read adjustment chart (Using examples).
1. Measure the present alignment.
Standard camber: -0°20' (-0.33°)
Standard caster: 3°15' (3.25°)
2. Mark the difference between the standard value (A) and the measured value (B) on the adjustment chart.
Standard value:
Camber: 0°00' (0°)
Caster: 3°05' (3.08°)
Formula: A - B = C
Camber: 0°00' - (-0°20') 0°20'
Caster: 3°05' -3°15' = -0°10'
3. As shown in the chart, read the distances from the marked point to the 0 point, and adjust the front and/or rear adjusting cams accordingly
Front cam: - (Shorter) 1.6
Rear cam: - (Shorter) 3.2
d. Torque the front and/or rear adjusting cam nuts.
Torque: 98 Nm (1,000 kgf-cm, 72 ft. lbs.)
6. ADJUST TOE-IN
a. Check or adjust the lengths of the rack ends, then adjust the toe-in.
Standard rack end length difference: 3.0 mm (0.118 inch) or less
b. Remove the boot clamps.
c. Loosen the tie rod end lock nut.
d. 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.
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 clamps.
HINT: Make sure that the boots are not twisted.
g. Perform the VGRS system calibration.
h. Perform the 0 point calibration of the yaw rate and deceleration sensor.
7. INSPECT AND ADJUST WHEEL ANGLE
a. Turn the steering wheel fully to the right and left, and measure the turning angle.
Standard Wheel Turning Angle:
If the right and left inside wheel angles differ from the specified value, check the right and left rack end lengths.
b. When toe-in is normal after inspection, adjust wheel angle with the knuckle stopper bolt of the lower suspension arm.
Torque: 44 Nm (450 kgf-cm, 32 ft. lbs.)
