For 1983-88 vehicles, there are no alignment adjustments for the rear wheels. For 1989-96 vehicles, the camber and toe are adjustable on the rear of these vehicles. If any parts were removed or replaced on the rear suspension, have the wheel alignment checked and adjusted at a qualified alignment shop.
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 angle is the number of degrees that a line drawn through the suspension knuckle pivots is inclined from the vertical, toward the front or rear of the car (when viewed from the side of the car). Caster improves the directional stability and decreases susceptibility to crosswinds or road surface deviations.
Toe-in and toe-out is the difference in the distance between the extreme front and the extreme rear of the tires. Toe-in occurs when the dimension taken at the front of the tires is less than that taken at the rear of the tires equals positive toe. Toe-out occurs when the dimension taken at the front of the tires is greater than that taken at the rear of the tires equals negative toe.
