What is adjusted to correct a vehicle that pulls to one side while driving?

When a vehicle pulls to one side while driving, the adjustment that is typically made is to the toe alignment. The toe refers to the angle of the wheels in relation to the centerline of the vehicle when viewed from above. If the wheels are misaligned in this respect—either pointing inwards or outwards—this can cause the vehicle to pull toward one side.

Adjusting the toe settings can help ensure that both front wheels are aligned in the same direction, which allows for more stable and straight driving. Proper toe alignment minimizes scrubbing of the tires and optimizes steering response and handling characteristics, thereby addressing the pulling issue effectively.

While camber and caster also play crucial roles in vehicle alignment, their primary impacts are different. Camber affects the tilt of the wheels when viewed from the front, which influences cornering performance rather than straight-line pulling. Caster involves the angle of the steering axis and plays a role in steering stability and returnability but does not directly correct lateral pull. Shock absorbers, while important for managing ride quality and handling, do not affect wheel alignment and thus do not correct pulling issues.
