Abstract
A method of making a wheel end to be installed on a vehicle includes assembling a rotor and components with bearing surfaces to define an assembled module configured to be mounted to the vehicle, and preloading the bearing surfaces of the assembled module in a set amount as required for mounting the assembled module to the vehicle. The method further includes mounting the assembled module on a holding fixture and rotating the assembled module on the holding fixture. The method further includes, while rotating the preloaded assembled module, machining the face of the hub flange prior to affixing a rotor to the flange, and then machining a final cut on the rotor once the rotor is affixed to the flange. After machining, the assembled module remains preloaded with the set amount of preload as the assembled module is installed on the vehicle, thereby providing reduced lateral runout.
