The front wheels aim or steer the vehicle. The rear wheels control tracking. This tracking action relates to the thrust angle. The thrust angle is the path that the rear wheels take. Ideally the thrust angle is geometrically aligned with the body centerline. If, for example, the toe-in on the left rear wheel is out of specification, it moves the thrust line off center. The resulting deviation from the centerline is the thrust angle.
