Wheel Alignment Angles: Caster
Caster is the deviation from vertical of an imaginary line drawn through the pivot points (top of strut and lower ball joint), when viewed from the side. The caster specifications in this service information will give the vehicle the best directional stability characteristics when loaded and driven. The caster setting is not related to tire wear. The caster setting is not adjustable.
A backward tilt is positive (+) and a forward tilt is negative (-). Front caster adjustment is not a separate procedure on this vehicle. The vehicle will tend to drift/pull toward the side with the lowest caster.
