Claim 0:
1. A noise vibration harshness reduction assembly comprising:
a housing that defines a hole along a central axis;
a component supported via the housing and movable relative to the housing, wherein:
the component includes a bearing disposed in the hole;
the bearing includes a first race fixed to the housing and a second race rotatable relative to the first race about the central axis;
the first race of the bearing includes a radial side that faces away from the central axis and an axial side disposed transverse to the radial side such that the radial side and the axial side are adjacent to each other;
the housing includes a shoulder that extends along the radial side of the bearing and extends along the axial side of the bearing; and
the housing includes an axial wall that faces the axial side of the bearing; and

an axial ring disposed axially along the bearing of the component relative to the central axis, and wherein:
the axial ring includes an axial body disposed axially along the first race relative to the central axis;
the axial body of the axial ring includes a plurality of axial corrugations; and
the axial corrugations engage the axial side of the bearing and the axial wall of the housing to stabilize the bearing when a low load is applied axially to the bearing; and
the axial ring is configured to attenuate axial sound inducing vibrations in response to operation of the component.
