Caster Adjustment
NOTE:
Jounce vehicle several times to settle suspension. Release on down stroke. Check for proper tire pressure, worn steering or suspension components.
- 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. Difference between front and rear shim pack should not exceed .40" (10.2 mm).
- To decrease caster (negative), add shims to front and remove from rear bolt. Tighten control arm shaft nuts, starting with thin shim pack first. Recheck caster. See Figure .
