The invention provides for a power steering apparatus comprising of a housing that extends along a longitudinal axis. A rack is disposed within the housing and supported for movement along the longitudinal axis by a bearing. A pinion supported by the housing is in meshing engagement with the rack. The bearing disposed around the rack includes a wall of a continuous varying radial thickness that circumferentially surrounds the rack. An adjustment device supported by the housing is connected to the bearing and rotatably adjusts the bearing relative to the longitudinal axis. The continuous varying radial thickness of the wall positions the rack as the bearing is rotated by the adjustment device relative to the pinion ensuring proper meshing engagement between the rack and the pinion.
