The guide assembly includes a guide bracket configured to engage the threaded member such that the threaded member moves with the guide assembly as the guide assembly moves along a path defined by a longitudinal axis of the elongated support member. This movement raises or lowers a vehicle positioned on the jack.

Rotation of the elongated support member about its longitudinal axis causes the threaded member to move the guide bracket along a path defined by the longitudinal axis.
