Alignment: Service and Repair
Wheel Alignment
The suspension can be adjusted for front camber, front toe, and rear toe. However, each of these adjustments are related to each other. For example, when you adjust camber, the toe will change. Therefore, you must adjust the front wheel alignment whenever you adjust camber or toe.
Pre-Alignment Checks
For proper inspection and adjustment of the wheel alignment, do these checks:
1. Release the parking brake to avoid an incorrect measurement.
2. Make sure the suspension is not modified.
3. Make sure the fuel tank is full, and that the spare tire, the jack, and the tools are in place on the vehicle.
4. Check the tire size and tire pressure.
5. Check the runout of the wheels and tires Testing and Inspection.
6. Check the suspension ball joints (Raise and support the vehicle Service and Repair. Hold a tire with your hands, and move it up and down and right and left to check for movement).
7. Before doing alignment inspections, be sure to remove all extra weight from the vehicle, and no one should be inside the vehicle (driver or passengers).
8. Lower the vehicle to the ground. Bounce the vehicle up and down several times to stabilize the suspension.
Caster Inspection
Use commercially available computerized four wheel alignment equipment to measure wheel alignment (caster, camber, toe, and turning angle). Follow the equipment manufacturer's instructions.
1. Check the caster angle.
- If the measurement is within specifications, measure the camber angle.
- If the measurement is not within specifications, check for bent or damaged suspension components.
Camber Inspection
Use commercially available computerized four wheel alignment equipment to measure wheel alignment (caster, camber, toe, and turning angle). Follow the equipment manufacturer's instructions.
1. Check the camber angle.
- If the measurement is within specification, measure the toe-in.
- If the measurement for the front camber is outside the specification, go to front camber adjustment.
- If the measurement for the rear camber is outside the specification, check for bent or damaged suspension components.
Front Camber Adjustment
The front camber can be adjusted by exchanging one or both of the damper pinch bolts with a smaller diameter adjusting bolt. The difference between the adjusting bolt diameter and the pinch bolt hole diameter allows for a small range of adjustment.
NOTE: Refer to the Parts Catalog if you need to use an adjusting bolt.
1. Raise and support the vehicle Service and Repair.
2. Remove the front wheels.
3. Loosen the damper pinch bolts (A), and adjust the camber angle by moving the bottom of the damper within the range of the damper pinch bolt free play.
4. Tighten the damper pinch bolts while holding the flange nuts to the specified torque.
5. Reinstall the front wheels. Lower the front of the vehicle to the ground, and bounce the front of the vehicle up and down several times to stabilize the suspension.
NOTE: Before installing the wheel, clean the mating surfaces between the brake disc and the inside of the wheel.
6. Measure the camber angle.
- If the measurement is within specification, measure the toe-in.
- If the measurement is not within specification, go to step 7.
7. Raise and support the vehicle Service and Repair.
8. Remove the front wheels.
9. Replace the damper pinch bolts with the adjusting bolts (A), and adjust the camber angle.
NOTE:
- The camber angle can be adjusted up to ±20 ' (center of tolerance) by replacing one damper pinch bolt with the adjusting bolt.
- The camber angle can be adjusted up to ±40 ' by replacing both damper pinch bolts with the adjusting bolts.
10. Tighten the adjusting bolts while holding the flange nuts to the specified torque.
11. Install the front wheels.
NOTE: Before installing the wheel, clean the mating surfaces between the brake disc and the inside of the wheel.
12. Lower the vehicle to the ground, and bounce the front of the vehicle up and down several times to stabilize the suspension.
13. Measure the camber angle. If the camber angle is not within specification, check for damaged or bent suspension components. If the camber measurement is correct, measure the toe-in, and adjust it if necessary.
Rear Toe Inspection/Adjustment
Use commercially available computerized four wheel alignment equipment to measure wheel alignment (caster, camber, toe, and turning angle). Follow the equipment manufacturer's instructions.
1. Release the parking brake to avoid an incorrect measurement.
2. Check the toe.
- If adjustment is required, go to step 3.
- If no adjustment is required, go to front toe inspection/adjustment.
3. Hold the adjusting bolt (A) on the rear trailing arm, and loosen the self-locking nut (B).
NOTICE
Do not loosen the special bolts (C) on the trailing arm.
4. Replace the self-locking nut with a new one, and lightly tighten it.
NOTE: Always use a new self-locking nut whenever it has been tightened to the specified torque.
5. Adjust the rear toe by turning the adjusting bolt until the toe is correct.
6. Tighten the self-locking nut while holding the adjusting bolt to the specified torque.
Front Toe Inspection/Adjustment
Use commercially available computerized four wheel alignment equipment to measure wheel alignment (caster, camber, toe, and turning angle). Follow the equipment manufacturer's instructions.
1. Center the steering wheel spokes, and install a steering wheel holder tool.
2. Check the toe with the wheels pointed straight ahead.
- If adjustment is required, go to step 3.
- If no adjustment is required, remove the alignment equipment.
3. Loosen the tie-rod end locknuts (A) while holding the flat surface sections (B) of the tie-rod end with a wrench, and turn both tie-rod arm (C) until the front toe is within specifications.
4. After adjusting, tighten the tie-rod end locknuts to the specified torque. Reposition the rack-end boot if it is twisted or displaced.
Turning Angle Inspection
Use commercially available computerized four wheel alignment equipment to measure wheel alignment (caster, camber, toe, and turning angle). Follow the equipment manufacturer's instructions.
1. Turn the wheel right and left while applying the brake, and measure the turning angle of both wheels.
2. If the measurement is not within the specifications, even up both sides of the tie-rod threaded section length while adjusting the front toe. If it is correct, but the turning angle is not within the specifications, check for bent or damaged suspension components.
