Abstract: A locking device for holding a hub bearing on a spindle. When locking the hub bearing into place, the wheel which sits on the hub and rotates around the spindle is also stabilized. The locking device replaces the traditional circular three-piece combination fastener predominately used in the commercial trucking industry. This locking device can be utilized as a replacement on spindles already on the highway, or it can be incorporated at the manufacture of the tractor or the trailer. And the present locking device can be utilized on any compatibly grooved spindle.
