A process for manufacturing and assembling a corner assembly for a vehicle to achieve a perpendicular relationship between an axle of a vehicle and first and second braking surfaces on a rotor. In this process, after an inner race of a bearing is pressed onto a wheel hub and an outer race is pressed into a support structure to define a sub-assembly. The sub-assembly is placed onto a locating fixture such that the outer race supports the sub-assembly in a desired alignment where an out board surface on a radial flange is in a perpendicular relationship with the axis of the wheel hub. An arbor is inserted into an axle bore surrounding the axis of the wheel hub and the sub-assembly is rotated on the inner race to simulate operational condition of a vehicle as the surface of the out-board flange is finished machined to define a perpendicular relationship with the axis of the wheel hub. Once the out board surface is finish machined, the wheel hub is in a condition to receive a rotor by bringing an alignment surface on the rotor into engagement with the finished surface of the wheel hub. The rotor is retained on the hub through studs that extend from the wheel hub for attaching a wheel to the wheel rotor. The wheel hub is located such that radial braking surfaces on the rotor are in perpendicular planes with respect to the axis of the axle and parallel to the surfaces of the friction pads.
