How are wheels aligned?
A. Alignment involves adjusting the angles of the wheels so that they are parallel to each other and perpendicular to the ground. The three main adjustments made in alignment are Camber, Caster, and Toe. Camber Camber is the angle of the wheel, in degrees, when viewed from the front of the vehicle. Positive camber is when the top of the wheel is leaning out from the center of the car. Negative camber is when the top of the wheel is leaning into the car. If the wheel leans too far from the center, uneven wear will occur. The camber angle is designed and adjusted per vehicle to keep the tires on the outside of a curve flat on the ground during a turn. If you have too much positive camber, your tires will wear on the outside. Too much negative camber will wear them on the inside. If there is too much of a difference between the camber settings on the front wheels, the vehicle will tend to pull sharply to one side. Caster Caster is the forward or rearward tilt of the steering axis, measure
