Abstract
A wheel hub has inboard and outboard bearings separated by a spacer. A temporary alignment member is located against an inner surface of the spacer and an inner surface of the outboard bearing thus aligning the inner surfaces of the spacer and the bearing. A cap is located on an outboard surface of the hub to hold the outboard bearing in place. The cap includes a hole large enough for the alignment member to pass through. The hub may be easily mounted onto an axle merely by locating an inboard opening of the hub over the axle and sliding the hub onto the axle. As the axle enters the hub it eventually contacts the alignment member and begins moving the alignment member outward through the hole in the cap. As the alignment member moves outward the axle refills the space immediately vacated by the alignment member. The hub is then further pushed onto the axle so that the alignment member falls away and the axle protrudes through the hole in the cap. The cap is then removed and a nut is installed on the axle and tightened.
