ABSTRACT:
A tool particularly useful for facilitating the removal of a torsion bar employed as a spring element, particularly in automobiles such as the familiar Volkswagon rear-engine models. The torsion bar exerts a normal torque holding a spline-connected cantilever bar against a stop integral with a fixed structural member. The tool engages the arm adjacent its cantilevered end and applies a force increasing the torsion bar reaction force sufficient to dislodge it from the stop so that the cantilever bar can be forced outwardly by separate means to disengage the torsion bar-to-cantilever arm spline connection by a sufficient amount to allow controlled de-torquing rotation of the arm without encountering the stop. The spline connection may be subsequently fully disengaged and the torsion bar removed from its internal structural anchor. The tool includes an elongated closed frame forming an internal pocket within one end, a jack situated within the internal pocket and engagement hardware at the other end of the frame for connecting to a structural member of the vehicle.
