Various embodiments of a vehicle jack an include an elevation assembly and a guide bracket. The elevation assembly includes a threaded member and an elongated support member, with the elongated support member configured to threadedly engage and rotate relative to the threaded member. 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. Various embodiments address the assembly of a vehicle jack by engaging a threaded member with an elongated support member and a guide bracket. 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.
