Knuckle hub assembly and method for making same

摘要

A knuckle hub assembly ( 10 ) and a method for manufacturing same whereby brake run out is produced includes a knuckle ( 12 ), a bearing ( 28 ) press fit into the knuckle ( 12 ), and a wheel hub ( 14 ) coupled to the bearing ( 28 ) and rotateable with respect to the knuckle ( 12 ). The wheel hub ( 14 ) has a flange surface ( 34 ) having a relief channel ( 60 ) formed therein. A plurality of wheel studs ( 44 ) are press fit into bolt opening ( 42 ) formed in the relief channel ( 60 ). This arrangement provides a flat flange surface ( 34 ) for mating with a rotor ( 42 ) to minimize brake run out. The knuckle hub assembly ( 10 ) is mounted into a floating tool for finish turning of the flange surface ( 34 ) to provide minimal run out and maximum flatness.
