Setback Description

The setback applies to both the front and the rear wheels. The setback is the total amount of degree difference between one wheel spindle to the other. The road hazards or the collision damage can cause Setback. One of the first signs of setback is the difference between the caster readings from the wheel to the wheel and usually will be more than one degree of difference.
