Abstract
The present invention is a tool that removes hub seals from wheel hubs. The tool comprises a blade having a flat surface, a tapered surface, a flat side, a tip edge, and a handle attached to the blade. The flat side is connected to the tip edge to form a corner, which is suitable for insertion into an annular space between the hub seal and bearings on the hub. In order to remove the hub seal, the blade is inserted into the annular space, force is applied to the handle, and leverage is used to remove the hub seal. The blade is formed so as to be strong enough to withstand the force applied to remove the hub seal yet thin enough to fit into the annular space of wheel hubs.
