Abstract
A hub puller device to simplify the removal of the hub from the wheel bearing on front wheel drive cars when maintenance is required. In the preferred embodiment, the device includes a U-shaped frame, a forcing screw, traveling nut and a pushing piece. A maintenance technician installs the forcing screw to extend through the open cylindrical section of the hub and mounts the pushing piece and the traveling nut on the forcing screw adjacent the cylindrical section. Next, the technician installs the frame to wrap around the spindle housing such that one member abuts the front surface of the spindle housing. The other frame member braces the receiving end of the forcing screw and prevents linear movement of the forcing screw. With the setup completed, the maintenance technician rotates the forcing screw and prevents rotation of the traveling nut. The rotational motion of the forcing screw is translated to linear movement of the traveling nut, which pushes against the pushing piece to eject the cylindrical portion of the hub from the wheel bearing.
