  • Patent number: 9009938
    Abstract: A tool for removing a spindle and/or elastomeric bearing from a hub generally includes a coupler, an arm, and a weight slidably engaged with the arm. The weight is slidable with respect to the arm along a predetermined stroke that limits the travel of the weight. The coupler may be secured to a spindle, which spindle is in turn secured to a bearing, or the coupler may be secured directly to the bearing. An operator may slide the weight between a first position adjacent the coupler and a second position opposite the coupler to impart kinetic energy to the spindle and/or bearing, thereby removing the bearing from or the bearing installing into a hub, depending on whether the kinetic energy is in an inboard or outboard direction.

  • Publication number: 20100283016
    Abstract: 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.
