The invention provides for a power steering apparatus (30) comprising of a housing (32) that extends along a longitudinal axis (42). A rack (34) is disposed within the housing (32) and supported for movement along the longitudinal axis (42) by a bearing (40). A pinion (36) supported by the housing (32) is in meshing engagement with the rack (34). The bearing (40) disposed around the rack (34) includes a wall (66) of a continuous varying radial thickness that circumferentially surrounds the rack (34). An adjustment device (38) supported by the housing (32) is connected to the bearing (40) and rotatably adjusts the bearing (40) relative to the longitudinal axis (42). The continuous varying radial thickness of the wall (66) positions the rack (34) as the bearing (40) is rotated by the adjustment device (38) relative to the pinion (36) ensuring proper meshing engagement between the rack (34) and the pinion (36).
