Abstract: A method of assembling a vehicle road wheel includes providing a tool fixture configured to support a press-fit load and arranging on the tool fixture an isolation plate defining a plate fastener aperture and having a locating projection. The method additionally includes arranging on the isolation plate a wheel subassembly having a hub surface and an opposing fastener surface and defining a hub aperture and a wheel fastener aperture, such that the hub surface rests against the isolation plate. The method also includes aligning the hub aperture with the locating projection and the wheel fastener aperture with the plate fastener aperture. The method additionally includes installing an insert into the wheel fastener aperture and engaging the insert with the plate fastener aperture. Furthermore, the method includes applying a load to the insert to press-fit the insert into the isolation plate at the plate fastener aperture and thereby assemble the wheel.

Abstract: A brake rotor for a braking system of a motor vehicle is provided. The brake rotor includes a disc section for rotating about a longitudinal axis and engaging a brake pad assembly. The brake rotor further includes a hat section for attaching to a wheel. The hat section has a stepped surface spaced from the disc section along the longitudinal axis, and the stepped surface defines a recess for spacing the wheel and a portion of the stepped surface from one another when the wheel is attached to the hat section.
