Abstract
Abstract A method and apparatus for correcting misalignment resulting from a bent strut in a motor vehicle without requiring dismantling. The wheel support and alignment portion of a vehicle includes a wheel supporting hub, a wheel drum through which the hub extends and the strut which is connected between the hub and the frame of the vehicle. The technique comprehends the steps of holding the strut at a point adjacent the portion thereof to be bent, and applying a bending force to the portion of the hub which extends through the wheel drum. A wheel holding device is preferably connected to the wheel drum via the wheel's threaded bolts and lug nuts. The wheel holder has a horizontally extending thrust plate against which the piston of a jack is applied to push either upwardly or downwardly as the correction may require. An auxiliary U-shaped frame may be utilized to support the bending jack when a downward bending force is desired. Novel strut holders are provided to support the strut adjacent the position at which the bend is desired, and may include means for accommodating the ball joint and lower arm without doing damage thereto. Auxiliary clamping members, holding jacks and support members, including a movable base, may be provided in order to facilitate the alignment operation.
