Alignment Checks
ALIGNMENT CHECKSNOTE:
- 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.
- 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.
- Check the suspension ball joints. (Hold the wheel with your hands, then move it up and down, and right and left, to check for wobbling.)
1. Check the caster angle.
Caster angle: 3°00'±1°
2. if out of specification, record the caster reading, then adjust the caster.
3. Check the camber angle.
Camber angle:
- Front: (0°00'+ 1°) -1° to +1°.
- Rear: (-0°30'+ 30') -1° to 0°.
4. If out of specification, check for bent or damaged suspension components.
5. Center the steering wheel spokes.
6. Check the toe with the wheels pointed straight ahead.
Front toe: 0 ± 2 mm (0 ± 1/16inch) -0.06 to +0.06 inch
a. If adjustment is required, go on to step 4.
b. If no adjustment is required, remove alignment equipment.
7. Loosen the tie-rod locknuts, then turn both tie-rods in the same direction until the front wheels are in straight ahead position.
8. 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.
9. Release 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: 0 ± 2 mm (0 + 1/16 inch) -0.06 to +0.06 inch.
a. If adjustment is required, go to step 2.
b. If no adjustment is required, remove alignment equipment.
10. Hold the adjusting bolt on the rear lower arm B and loosen the self-locking nut.
11. Adjust the rear toe by turning the adjusting bolt until toe is correct.
12. Install the self-locking nut, and tighten it while holding the adjusting bolt.
13. Turn the wheel right and left while applying the brake, and measure the turning angle of both wheels.
Turning angle:
- Inward wheel: (39°00'+ 2°) +37° to +41°.
- Outward wheel (reference): 30°00'
14. If the turning angle is not within the specifications, check for bent or damaged suspension components.
