3. What is camber, caster, and toe?
When the camber is misaligned, it can lead to premature wear on one side of the tread and a pulling problem to the more positive camber. Some reasons that the camber may be misaligned is that the vehicle was in an accident, the springs sag caused a change in the ride height, or the ball joints/other attached parts are worn or defective.
When the caster is misaligned, in can cause problems with the straight-line tracking. Poor returnability of the steering wheel when it spins back to the straight-ahead position, too heavy steering or too light steering, leading to wandering and difficulties keeping in a straight line.
The vehicle’s toe is the most critical alignment settings that affect tire wear. A slight misalignment of the toe can result in a reduction in tire life. An increased toe in can reduce oversteer, steady the car, and enhance high speed stability. Increase toe out will also reduce understeer and free up the car.
