Caster
CASTERNOTE: 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.
1. Check the caster angle. Caster angle: (3°00'±1°) +2° to 4°.
2. If out of specification, record the caster reading, then adjust the caster.
NOTE: Caster angle can be adjusted by increasing or decreasing the number of the adjusting shims. Remove and install the radius rod each time the caster angle is adjusted.
1. Raise the front of the vehicle, and support it with safety stands in the proper locations.
2. Remove the self-locking nut on the end of the radius rod.
3. Remove the flange bolts at the radius rod on the lower arm, then remove the radius rod.
4. Adjust the caster angle by increasing or decreasing the adjusting shims.
NOTE:
- Do not use more than two adjusting shims.
- One adjusting shim changes the caster angle by 35' end the caster angle can be adjusted by 1°10' maximum.
- One adjusting shim is 3.2 mm (0.13 inch) in thickness.
5. After the adjustment, install the radius rod onto the lower arm, then tighten the flange bolts.
6. Tighten the new self-locking nut to specified torque.
