CASTER ADJUSTMENT
Loosen nuts attaching upper control arm pivot shaft to frame. To increase caster (positive), remove shims from front bolt and add them to rear bolt. To decrease caster (negative), add shims to front and remove from rear bolt. Tighten control arm shaft nuts and recheck caster. (Scheme 1)
CAMBER ADJUSTMENT
Loosen nuts attaching upper control arm pivot shaft to frame. To increase camber (positive), remove equal thickness of shims from front and rear bolts. To decrease camber (negative), add equal thickness of shim to front and rear bolts. Tighten control arm shaft and nuts and recheck camber. (Scheme 1)

Front Wheels
Toe-in can be changed by changing the length of tie rods. When tie rods are mounted ahead of steering knuckle they must be decreased in length in order to increase toe-in.
- Loosen clamp bolts at each end of steering tie rod adjustment sleeve. On models with rack and pinion steering loosen jam nut. With steering wheel set in straight ahead position, turn tie rod adjusting sleeves to obtain the proper toe-in adjustment.
- When adjustment is completed, check to see that the number of threads showing on each end of sleeve are equal and that tie rod end housing are at right angles to steering arm. Position tie rod clamps and sleeves. (Scheme 2) Tighten to specifications. On rack and pinion models tighten jam nut when set to proper specifications.
