Front Caster and Camber Adjustment
- The caster and camber adjustments are made by rotating the offset cam bolt and the cam in the slotted frame bracket in order to reposition the control arm.
- For an accurate reading, do not push or pull on the tires during the alignment process.
- Determine the caster angle (2).
- Determine the positive camber (2) or negative camber (3) angle.
- Lift the front wheels on the alignment rack prior to camber adjustment.
- Remove the pinned adjusting cam insert. Do not reinstall the cam insert.
- Loosen the lower control arm cam adjustment bolts.
- Adjust the caster and the camber angle by turning the cam bolts until the specifications have been met. Wheel Alignment Specifications

Caster measurements are now relative to ground.
Before adjusting the caster and camber angles, jounce the front bumper 3 times to allow the vehicle to return to normal height. Measure and adjust the caster and the camber with the vehicle at curb height. The front suspension Z dimension is indicated in Trim Heights. Trim Height Inspection
Lift the front wheels of the vehicle prior to adjusting camber. Lifting the front wheels minimizes force on the cam adjustment pin during camber adjustment. Failure to lift the front wheels prior to camber adjustment can result in damage to the cam adjustment pin.
Refer to Fastener Caution .
If the pin is missing, a 1/4 inch dowel rod or a punch can be utilized as a temporary alignment aid to properly center the cam to the bracket, while making adjustments and torquing the control arm nuts.
