Camber & Caster Adjustment

NOTE: The upper arm-to-frame mounting bolts have set shims that must be replaced with washers (W-705040-S900) to allow for adjustment of the arm in the frame slot. The vehicle should be supported by the lower arm to ease movement of the upper arm in the slot.

Remove the nuts and shims.

To adjust the caster and camber refer to the following chart.

Tighten the nuts.
NOTE: A caster split adjustment can be made on vehicles equipped with a two-piece RH upper control arm. This adjustment should only be used if steps 1-4 have been carried out and the side-to-side caster specification has not been achieved.
To decrease the RH caster, loosen the nuts and adjust, moving the ball joint forward.
