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 interrelated to each other. For
example, when you adjust toe, the camber changes. 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. Check the tire size and tire pressure.
Tire size:
Front/rear:
P185/70R14 87S
P185/65R15 86H
P195/60R15 87H
Tire pressure:
Front/rear:210 kPa (2.1 kgf/cm2, 30 psi)
4. Check the runout of the wheels and tires.
5. 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).
6. Bounce the vehicle up and down several times to stabilize the suspension.
Front 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.
Check the caster angle. If the caster angle is not within the specification, check for bent or damaged suspension components.
Front caster angle:
1°33' ± 1° for '01-02 models
2°14' ± 1° for '03-04 models
Front 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.
Check the camber angle. If the camber angle is not within the specification, adjust the camber.
Front camber angle: 0°00' ± 45'
Front Camber Adjustment
The front camber can be adjusted by exchanging one or both of the damper pinch bolts with the smaller diameter adjusting bolt(s). The difference
between the adjusting bolt diameter and the pinch bolt hole diameter allows a small range of adjustment.
