  • Patent number: 4507838
    Abstract: A tool for removing and replacing automobile wheelbearings without removing either the axle or the bearing housing and without applying pressure to the axle. A frame is provided which is adapted to be secured to the bearing housing. An extractor is movably connected to the frame to travel between an advanced and retracted position. When the frame is secured to the bearing housing, the advanced position of the extractor places it in the bearing housing between the axle and the central opening of the bearing, with the end of the extractor being past the bearing. The end of the extractor is operable between an expanded and retracted state. In its expanded state, the end of the extractor cannot be moved through the central opening of the bearing and thus moving the extractor to its retracted position while it is expanded will draw the bearing out of the housing.
