ABSTRACT:
An adapter for a jack is used in front end alignments to jack up a vehicle in a safe position. The adapter includes a generally horizontally extending elongated rocker arm, with a jack attachment member pivotally secured near the center of the rocker arm. The jack attachment member extends downwardly from the underside of the rocker arm for attachment to the ram of a jack placed on a wheel alignment rack below the front steering control arm of the vehicle. The rocker arm extends laterally away from both sides of the ram. An inner end of the rocker arm is attached to the generally horizontal underside of the steering control arm immediately inside the wheel of the vehicle. This provides a safe location at which to jack up the vehicle. The outer end of the rocker arm is pivotally attached to the top of an elongated upright support arm. A rack attachment member fastens the bottom of the support arm to the wheel alignment rack. This maintains the outer end of the rocker arm at a fixed elevation as the rocker arm pivots upwardly through an angle in response to the vertical stroke of the jack. The vertical force of the jack is transferred to the inner end of the rocker arm to raise upwardly against the safe location on the steering control arm. The inner end of the rocker arm has a bracket for securely fastening the rocker arm to the steering control arm. The bracket is adapted to rock about an axis transverse to the length of the rocker arm for securely attaching to the control arm as the rocker arm is being raised.
