Alignment
NOTE: For proper inspection/adjustment of the wheel alignment, check and adjust the following before checking the alignment.^ Check that the suspension is not modified.
^ Check the tire size and tire pressure.
^ Check the runout of the wheels and tires.
^ Check the suspension ball joints. (Hold a wheel with your hands and move it up and down and right and left to check for wobbling.)
WHEEL ALIGNMENT ADJUSTMENT PROCEDURE
Each of the wheel alignment elements relates to the other. Therefore, the total adjustment of the front/rear wheel alignment is required whenever either one of elements (i.e. camber, caster, toe, and/or turning angle) is adjusted.
Camber Inspection
NOTE: Use commercially available computerized four wheel alignment equipment to measure wheel alignment (i.e. toe, turning angle, camber, and/or caster). Follow the equipment manufacturer's instructions.
1. Check the tire pressure.
2. Turn the front wheels to the straight ahead position.
3. Check the camber angle.
Camber angle:
Front: 0° 00' ± 1°
Rear: 0° 45' ± 1° (2WS)
0° 45' ± 30' (4WS)
4. Front: If out of specification, check for damaged suspension components.
Rear: (2WS): If out of specification, check for damaged suspension components.
(4WS): If adjustment is required, go to step 5.
If no adjustment is required, remove alignment equipment or continue alignment.
Rear camber adjustment (4WS)
5. Hold the adjusting bolt and loosen the self-locking nut.
6. Adjust the rear camber by turning the adjusting bolt until camber is correct.
7. Install the new self-locking nut and tighten while holding the adjusting bolt.
Caster Inspection
NOTE: Use commercially available computerized four wheel alignment equipment to measure wheel alignment (i.e. toe, turning angle, camber, and/or caster). Follow the equipment manufacturer's instructions.
1. Turn the front wheels to the straight ahead position.
2. Check the caster angle.
Caster Angle: 2° 40' ± 1°
3. If adjustment is required, record the caster reading, then go to step 4. If adjustment is not required, remove alignment equipment.
NOTE: Caster angle can be adjusted by increasing/decreasing the number of the adjusting shims. Remove and install the radius rod each time the caster angle is adjusted.
4. Raise the front end of the car and place safety stands in the proper locations.
5. Remove the self-locking nut on the end of the radius rod.
6. Remove the radius rod attaching bolts at the lower arm, then remove the radius rod.
7. Adjust the caster angle by increasing/decreasing the adjusting shims.
- One adjusting shim changes the caster angle by 40' and the caster angle can be adjusted by 1° 20' maximum.
- One adjusting shim is 3.2 mm (0.13 in) in thickness.
NOTE:
^ Do not use more than two adjusting shims.
^ After the adjustment, tighten the self-locking nut to the specified torque.
Front Toe Inspection/Adjustment
NOTE: Use commercially available computerized four wheel alignment equipment to measure wheel alignment (i.e. toe, turning angle, camber, and/or caster). Follow the equipment manufacturer's instructions.
1. Check the tire pressure.
2. 2WS: Position the wheels pointed straight ahead.
4WS: Set the front main steering angle sensor in the neutral position and jump the service check connector to turn the 4WS indicator ON.
NOTE: Maintain this condition during inspection and adjustment.
3. Check the front toe.
Front toe: 0 ± 2.0 mm (0 ± 0.08 in)
- If adjustment is required, go on to step 5.
- If no adjustment is required, remove alignment equipment.
4. Loosen the tie-rod locknuts and turn both tie-rods in the same direction until the front wheels are in straight ahead position.
5. Turn both tie-rods equally until the toe is correct.
6. After adjusting, tighten the tie-rod locknuts.
NOTE: Reposition the tie-rod boot if it is twisted or displaced.
Rear Toe Inspection/Adjustment
NOTE: Use commercially available computerized four wheel alignment equipment to measure wheel alignment (i.e. toe, turning angle, camber, and/or caster). Follow the equipment manufacturer's instructions.
1. 4WS only: Check the rear main steering angle sensor is in the neutral position and jump the service check connector to turn the 4WS indicator ON.
NOTE: Maintain this condition during inspection.
2. Release parking brake.
3. Check the rear toe.
NOTE:
^ Measure difference in toe measurements with the wheels pointed straight ahead.
^ If the parking brake is engaged, you may get an incorrect reading.
Rear toe-in: 2.0 ± 2.0 mm (0.08 ± 0.08 in)
- If adjustment is required, go to step 4.
- If no adjustment is required, remove alignment equipment.
4. 2WS:
^ Hold the adjusting bolt on the rear lower arm B and loosen the self-locking nut.
^ Adjust the rear toe by turning the adjusting bolt until toe is correct.
^ Install the new self-locking nut and tighten while holding the adjusting bolt.
4WS:
^ Loosen the tie-rod locknuts and turn both tie-rods in the same direction until the rear wheels are in straight ahead position.
NOTE: Make sure the 4WS indicator is ON.
^ Turn both tie-rods equally until the toe is correct.
^ After adjusting, tighten the tie-rod locknuts.
NOTE: Reposition the tie-rod boot if it is twisted or displaced.
Turning Angle Inspection/Adjustment
NOTE: Use commercially available computerized tour wheel alignment equipment to measure wheel alignment (i.e. toe, turning angle, camber, and/or caster). Follow the equipment manufacturer's instructions.
1. Jack up the front of the car. Set the turning radius gauges beneath the front wheels, then lower the car.
2. 2WS: Jack up the rear of the car. Place boards that are the same thickness as the turning radius gauges under the rear wheels, then lower the car.
4WS: Jack up the rear of the car. Set the turning radius gauges beneath the rear wheels, then lower the car.
NOTE: For accurate readings, the car must be level.
3. Turn the wheel right and left while applying the brake. Measure the turning angle of both front wheels, and both rear wheels (4WS models).
Front turning angle:
Inward wheel: 36° 20' ± 2°
Outward wheel: 29° 40'
Rear turning angle (4WS):
Inward wheel: 6° 00' ± 1°
Outward wheel: 6° 20'
4. If the measurements are not within the specifications, adjust as required by turning the tie-rods.
NOTE: After adjusting, recheck the front wheel toe and readjust if necessary. Reposition the tie-rod boot if twisted or displaced.
