Alignment: Service and Repair

CASTER

NOTE: For proper inspection 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.)

Inspection

NOTE: Use commercially-available computerized four wheel alignment equipment to measure wheel alignment (caster, camber, toe, and/or turning angle). Follow the equipment manufacturer's instructions.

1. Check the caster angle.

Caster angle: 3°21' ± 1°

2. If out of specification, record the caster reading, then adjust the caster.

Adjustment

NOTE: Caster angle can be adjusted by increasing or decreasing the number of the adjusting shims. Remove and install the radius rod each time the caster angle is adjusted.

1. Raise the front of the vehicle, and support it with safety stands in the proper locations.
2. Remove the self-locking nut on the end of the radius rod.
3. Remove the flange bolts at the radius rod on the lower arm, and remove the radius rod.





4. Adjust the caster angle by increasing or decreasing the adjusting shims.

NOTE:
- Do not use more than two adjusting shims.
- One adjusting shim changes the caster angle by 35' and the caster angle can be adjusted by 1°10' maximum.
- One adjusting shim is 3.2 mm (0.13 inch) in thickness.

5. After the adjustment, install the radius rod onto the lower arm, and tighten the flange bolts.
6. Tighten the new self-locking nut to the specified torque.

CAMBER

Inspection
1. Check the camber angle.

Camber angle:
Front: 0°07' ± 1°
Rear: -0°12' ± 30'

2. If out of specification, check for bent or damaged suspension components.

FRONT TOE INSPECTION / ADJUSTMENT

NOTE: Use commercially-available computerized four wheel alignment equipment to measure wheel alignment (caster, camber, toe, and/or turning angle). Follow the equipment manufacturer's instructions.

1. Check the tire pressure.
2. Center steering wheel spokes.
3. Check the toe with the wheels pointed straight ahead.

Front toe: 0 ± 2 mm (0 ± 1/16 inch)

- If adjustment is required, go on to step 4.
- 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 reading on the turning radius gauge 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 (caster, camber, toe and/or turning angle). Follow the equipment manufacturer's instructions.

1. Release the parking brake.

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 ± 2 mm (1/16 ± 1/16 inch)

- If adjustment is required, go to step 2.
- If no adjustment is required, remove alignment equipment.
2. Hold the adjusting bolt on the rear lower arm B and loosen the self-locking nut.
3. Adjust the rear toe by turning the adjusting bolt until toe is correct.





4. Install the self-locking nut, and tighten it while holding the adjusting bolt.

TURNING ANGLE INSPECTION




1. Turn the wheel right and led while applying the brake, and measure the turning angle of both wheels.

Turning angle:
Inward wheel: 34°30' ± 2°
Outward wheel: 27°30' (reference).

2. If the turning angle is not within the specifications, check for bent or damaged suspension components.
