Definition of Terms
Camber
Camber is the inward or outward tilting of the front wheel 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 at the top, the camber is negative. Camber influences both directional control and tire wear
and will also cause a vehicle to pull or lead to one side (whichever wheel has the most positive camber). Refer to the image.
Caster
Caster is the tilting of the steering ball joint axis either forward or backward from the vertical when viewed from the side of the vehicle. A backward tilt
(from the top of the vehicle) is a positive degree of caster and a forward tilt is a negative degree of caster. Caster influences directional control of the
steering but does not contribute to 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 lead toward the side with the fewest degrees of positive caster. Refer to the image.
