Abstract: A tool for pushing a half shaft out from an opening in the hub of a motor vehicle and for installing a hub onto the half shaft. The tool includes a housing attached to the lug bolts of the hub and having an opening for receiving a drive screw. A contactor is secured to the forward end of the screw for abutting the outer end of the shaft. As the screw is rotated to move in a forward direction, the contactor in response moves longitudinally in the forward direction, to push the shaft out from the hub. To install the shaft in the hub, a rammer is secured to the bolts of the hub. The rammer includes a head end for abutting the area of the hub circumscribing the hub opening and an impact end. Upon applying a force to the impact end, the head end pushes the hub over the shaft. A cavity is formed rearward from the head end of the rammer to receive the outer end of the shaft when it extends outward from the hub.

Abstract: A tool for removing a coupling cap when disconnecting the universal joint from a yoke, and installing a coupling cap when connecting a universal joint to a yoke. The tool includes a pair of anvils spaced apart for supporting the universal joint and yoke in a fixed vertical position. When the tool is used for disconnecting the U-joint, a rod is provided including a bottom end having an outer lip encircling the mouth of a bore extending inward therefrom. The lip impacts the portion of the yoke circumscribing the opening containing the cap in press fit association with the U-joint and the yoke in response to a downward force acting on the rod, to cause the cap to dislodge from the opening and move upward into the bore of the rod. When the tool is used for connecting the U-joint to the yoke, the rod is provided including a piston at the bottom end thereof.

Abstract: A device for removing a hub and a bearing from a spindle of an automotive wheel drive, and also for pressing a bearing and a hub back into the spindle. The device includes a screw drive which is rotatable but does not move longitudinally when pulling the hub out from the bearing or pushing the bearing out from the spindle. A housing is secured to the hub and threadedly attached to the screw drive. The housing moves inward along the screw drive for pulling the hub out from the bearing, as the screw drive is rotated. A nut is threadedly attached to the screw drive and moves inward along the screw drive for pushing the bearing out from the spindle, as the screw drive is rotated. The rotatable screw drive is also utilized to move longitudinally toward the spindle for pressing the bearing back into the spindle and pressing the hub back into the bearing.
