Suspension System
Camber, caster and toe are adjustable on the front suspension system. Only the toe is adjustable on the rear suspension system. Camber and caster are
adjusted by means of eccentric cams on the lower control arm mounting bolts. The front toe is adjusted by use of the front wheel spindle tie rod. The
rear toe is adjusted by the use of toe link assemblies connecting the knuckles to the rear sub-frame.
Camber
Negative and Positive Camber
Negative and Positive Camber
Camber is the vertical tilt of the wheel when viewed from the front. Camber can be positive or negative and has a direct effect on tire wear.
Caster
Caster is the deviation from vertical of an imaginary line drawn through the ball joints when viewed from the side. The caster specifications will give
the vehicle the best directional stability characteristics when loaded and driven. The caster setting is not related to tire wear.
