Abstract: An axle assembly for supporting wheels is provided that has a spindle defining an axis of rotation with a threaded end portion. A hub assembly is supported by the spindle and is adapted to support the wheels. A bearing assembly is arranged adjacent to the threaded end portion and is interposed between the spindle and the hub assembly for permitting low friction rotation of the hub assembly relative to the spindle about the axis. An end nut is secured to the threaded end portion of the spindle for retaining the bearing assembly and the hub assembly on the spindle. A washer is interposed between said bearing assembly and the end nut wherein the washer secures the end nut to the spindle for preventing rotation of the end nut about the axis.
