Caster angle is the number of degrees that a line drawn through the steering knuckle pivots is inclined from the vertical, toward the front or rear of the vehicle. Caster improves directional stability and decreases susceptibility to crosswinds or road surface deviations.
Camber angle is the number of degrees that the centerline of the wheel is inclined from the vertical. Camber reduces loading of the outer wheel bearing and improves the tire contact patch while cornering.
Caster and camber are controlled by hexagonal cams which control the position of the lower ball joint on the control arm. Rotating the inner (caster) or outer (camber) cam by two flats changes caster or camber by 1°.
Caster and camber are not adjustable on these models. If either of these specifications is not within the factory recommended range, this would indicate bent or damaged parts that must be replaced.
