A powered cylinder secures to an upper end location of the leg and includes first and second telescoping components terminating in a clamp exhibiting a plurality of radially outwardly extending claws. The claws terminate in inwardly directed fingers for engaging respective locations along an annular rim associated with at least one of the outer and inner road wheel components. The clamp is adapted to engaging a location associated with the road wheel and in order to apply at least one of a pulling and twisting force to forcibly remove the road wheel from the hub.
