Wheel Alignment Specifications & Procedures: Adjustment: Caster: I-Mark
- Realign the washers located between legs of upper control arm. One 1/8" (3 mm) thickness washer and one 3/8" (9.5 mm) thickness washer must be used as a couple for caster adjustment.
- The replacement of washers requires the same outside diameter as those being changed. Combined total thickness of front and rear washers is 1/2" (12.7 mm). Only minimal changes to caster can be accomplished this way.
