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 the toe, the camber changes. Therefore, you must adjust the front wheel alignment whenever you adjust the 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: '02-03
Front/rear: 195/60R15 88V
Tire size: '04-05
Front/rear: 205/55R16 89V
Tire pressure: '02-03 models
Front: 230 kPa (2.3 kgf/cm2, 33 psi)
Rear: 210 kPa (2.1 kgf/cm2, 30 psi)
Tire pressure: '04-05 models
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: '02-03 models 1°40' ± 1°
Front caster angle: '04-05 models 1°35' ± 1°
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: '02-03 models - 0°30' ± 45'
Front camber angle: '04-05 models - 0°10' ± 45'
