The device further includes a slide hammer unit comprising a hammer weight slidable about a shaft, the slide hammer unit defining an adaptor at a proximal end that is configured for removably attaching to one of the first connector of the pull bar and the second connector of the wedge bar. In a storage mode, the adaptor is disengaged from the pull bar and the wedge bar.
