Alignment: Description and Operation
Alignment Rack Maintenance
Adjust the rack for level and calibration at the manufacturer's recommended intervals. Refer to the alignment rack manufacturer's operators guide for
information regarding adjustment.
Camber
Camber is the tilting of the wheels from the vertical when viewed from the front of the vehicle. When the wheels tilt outward at the top, the camber is
positive (+). When the wheels tilt inward, the camber is negative (-). The amount of tilt measured in degrees from the vertical is camber angle. Camber
influences both directional control and tire wear. Not only will excessive camber result in tire wear, but it will also cause the vehicle to pull or lead to the
side with the most positive camber. Camber adjustment is available at both front and rear wheels.
Caster
Caster is the tilting of the uppermost point of the steering axis, either forward or backward from the vertical, when viewed from the side of the vehicle. A
backward tilt (at the top) is positive (+) and a forward tilt is negative (-). Caster influences directional control of the steering but does not affect tire wear.
If one wheel has more positive caster than the other, it will cause that wheel to pull toward the center of the vehicle. This condition will cause the vehicle
to move or lead toward the side with the least amount of positive caster.
