Caster Adjustment
NOTE:
If caster adjustment is necessary to resolve a pull, or out of specification cross-caster split, then slotting the shock tower at the front shock absorber upper mounting point is an acceptable method. This procedure should not be routinely performed with all alignments and only after all other possible sources have been inspected and corrected as necessary.
- Determine the amount of caster adjustment needed. If no more than 0.6 degree is needed, only one shock tower needs to be slotted. Mark the camber position of the front suspension camber adjusting plate. See Fig 1 .
- Remove the nuts, bolt and the front suspension camber adjusting plate. Raise the front end. Position the strut and spring assembly out of the way.
- Cut slots perpendicular to the existing camber adjustment slots. See Fig 2
.
- Moving the top of the front shock absorber toward the rear of the vehicle will increase the caster reading for that side.
- Each millimeter of adjustment should yield approximately 0.12 degree of caster change.
- Do not cut slots any longer than 0.20" (0.5 mm) in any direction.
- Remove any burrs.
- Clean and paint any exposed metal.
- Position the strut and spring assembly. Lower the front end. Install the front suspension camber adjustment plate, bolt and nuts. Hand tighten the bolt and nuts.
- Align the camber marks and position the front suspension camber adjustment plate at the correct caster setting. Tighten the nuts and bolt to specification. See TORQUE SPECIFICATIONS .
