Caster

Wheel Alignment Caster

NOTE: For proper inspection/adjustment of the wheel alignment, check and adjust the following before checking the alignment






- Check that the suspension in 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 (that is, caster, camber, toe, and/or turning angle). Follow the equipment manufacturer's instructions.

1. Check the caster angle.
Caster angle: 3°OO' ± 1°
2. If out of specification, record the caster reading, then adjust the caster.






Adjustment

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

1. Raise the front of the car, and support it with safety stands in the proper locations.
2. Remove the self-locking Out On the end of the radius rod.
3. Remove the flange bolts at the radius rod Os the lower arm, and remove the radian rod
4. Adjust the caster angle by increasing/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° 1O' maximum.
- One adjusting shim is 3.2 mm (0.13 in) in thickness.

5. After the adjustment, install the radius rod onto the lower arm, and tighten the flange bolts 76 lbf.ft.
6. Tighten the new self-locking nut to specified torque.
