Abstract
A locking system including a lock washer, a nut, and a retainer which together act to secure a wheel hub to a spindle. The lock washer has a tab which extends through the nut and the retainer, and which wraps around and back over the retainer in order to axially and rotationally secure the retainer. The tab has an initial position that corresponds to an unlocked position and a distal end of the tab extends beyond the hub in the initial position far enough to prevent an end cap from being placed over the tab when the tab is in the initial position. As such, installation of the end cap is not possible until the tab is bent into a locked condition.
