Caster adjustment will help the vehicle maintain a straight line, making it easier for the driver to steer and maintain control. Caster refers to the tendency of a wheel to return to a straight path after a turn (think of how the wheels of a shopping cart are always oriented in the right direction). Learn how to adjust the turntables to keep irregular tire wear, and improve vehicle performance.
