Alignment: Description and Operation
WHEEL ALIGNMENT ANGLES
Caster and camber correction requirements are factory-determined. Adjusters are available to correct a caster/camber measurement that does not meet
specification. Before changing the production caster/camber adjuster, thoroughly inspect the suspension system to locate worn or damaged
components that may have caused the setting to change.
Negative and Positive Camber
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 and Frame Angle (Positive Caster Shown)
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.
