Wheel hub and bearing assembly packaging
A packaging system having an outboard guard and an outboard retainer cap. The outboard guard includes an outboard guard opening having a hole through the planform of the outboard guard, an engagement portion having an annular surface radially surrounding the outboard guard opening, an outboard bearing protector portion having an annular surface radially surrounding the engagement portion of the outboard guard, and an outer rim having an annular surface radially surrounding the outboard bearing protector portion. The outboard retainer cap is configured to be removably affixed to the outboard guard and includes an outboard alignment protrusion having a circular surface, an engagement portion having an annular surface radially surrounding the outboard alignment protrusion, and a retaining flange having an annular surface radially surrounding the engagement portion of the outboard retainer cap.
1. A method of installing a wheel hub assembly onto a vehicle spindle, the wheel hub assembly comprising a vehicle wheel hub having a wheel hub bore with an inboard side and an outboard side, the wheel hub bore being configured to accept the vehicle spindle, an inboard bearing assembly installed on an inboard side of the vehicle wheel hub and comprising an inboard bearing cone and inboard bearing elements, and an outboard bearing assembly installed on an outboard side of the vehicle wheel hub and comprising an outboard bearing cone and outboard bearing elements, the wheel hub assembly further comprising an outboard retainer cap removably affixed within an outboard guard by an interference fit between the outboard retainer cap and the outboard guard, the outboard guard being removably affixed to an outboard side of the vehicle wheel hub and retaining the outboard bearing assembly within the vehicle wheel hub, a portion of the outboard retainer cap extending through an opening in the outboard guard and into the outboard side of the wheel hub bore of the vehicle wheel hub, the wheel hub assembly further comprising an inboard guard removably affixed to an inboard side of the vehicle wheel hub and retaining the inboard bearing assembly within the vehicle wheel hub, the method comprising:
removing the inboard guard from the inboard side of the vehicle wheel hub to expose the wheel hub bore;
inserting the vehicle spindle into the wheel hub assembly from the inboard side of the wheel hub bore;
disengaging the outboard retainer cap from the outboard guard by force of the vehicle spindle within the wheel hub bore and against the outboard retainer cap in an outboard direction; and
continuing to insert the vehicle spindle into the wheel hub assembly until the vehicle spindle protrudes from the outboard side of the wheel hub bore.
2. The method of claim 1 , further comprising removing the outboard guard from the vehicle wheel hub before securing the wheel hub assembly onto the vehicle spindle.
3. The method of claim 2 , in which removing the outboard guard from the vehicle wheel hub comprises pulling on one or more pull tabs of the outboard guard in the outboard direction to extract one or more retainer clips of the outboard guard from hubcap mounting holes of the vehicle wheel hub.
4. The method of claim 1 , further comprising removing the outboard guard from the vehicle wheel hub after securing the wheel hub assembly onto the vehicle spindle.
5. The method of claim 4 , in which removing the outboard guard from the vehicle wheel hub comprises pulling on one or more pull tabs of the outboard guard in the outboard direction to extract one or more retainer clips of the outboard guard from hubcap mounting holes of the vehicle wheel hub.
