Front Caster Adjustment

Front Caster Adjustment
Use the following procedure in order to prepare the top strut mounting holes:





1. Remove the top 3 fasteners from the strut tower.
2. Lift the front of the vehicle by the body in order to separate the strut from the inner wheelhouse. Refer to Vehicle Lifting.





3. Pop out the 2 guide pins.
4. Hand file the excess metal in order to make slotted holes.
5. Paint the exposed metal using rust preventative paint or primer.
6. Lower the front of the vehicle.
7. Install the strut attaching fasteners. Do not tighten the fasteners at this time.

Notice: Refer to Fastener Notice in Service Precautions.

8. Move the top of the strut forward or rearward in order to adjust the caster. A 1 mm (0.040 inch) position change at the tower is about equal to a 0.1 degree change in the caster.
Tighten the strut fasteners to 47 Nm (35 ft. lbs.).
9. Perform a complete wheel alignment.
