Front Caster Adjustment
FRONT WHEEL CASTERIMPORTANT: The front wheel caster setting is fixed by body structure geometry and the fixed lengths of suspension components. Therefore, front caster should not vary under normal circumstances. If the caster angle is found to be out of specification, check for bent suspension components, bent body structure, worn front stabilizer bar bushings and proper alignment measuring techniques. Only when the above criteria are found to be correct, perform the following procedure:
1. Lock steering wheel in the straight ahead position.
2. Remove and discard strut assembly to body attachment nuts.
3. Slide strut forward or rearward in the body in the direction of desired caster angle change.
3.1. Move the top of the strut forward to decrease positive caster.
IMPORTANT: Moving the top of the strut 4 mm (0.157 inch) will result in approximately 1/2 degree of change in caster angle.
3.2. Move the top of the strut rearward to increase positive caster.
IMPORTANT: The body attachment holes may need to be riled or ground into oval slots to allow enough front/rear strut movement to adjust caster to specifications. Do not exceed 9 mm (0.354 inch) in the width of the slot.
IMPORTANT: If body was filed, paint exposed metal with primer.
4. Install new strut assembly -to- body attachment nuts.

5. Check caster angle. Re-adjust if necessary.
