Abstract: A novel, preassembled hub assembly is presented having all the standard components (including the inboard and outboard bearings, spacer, and lubricant seal) preassembled inside the hub at the manufacturing facility. In addition, the manufacturing facility also affixes a pre-positioned spindle nut assembly to the hub assembly. In this embodiment, the preassembled hub assembly (with the pre-positioned spindle nut assembly affixed to the hub) has no separate or loose parts, facilitating shipment and installation of the hub assembly. Installation only requires placement of the novel hub assembly on the spindle and the tightening of the factory installed, pre-positioned retaining nut.
