A first isolator, a second isolator and a first shim are provided wherein the first isolator is disposed between an inner surface of the housing and a first surface of an outer race of the bearing, the second isolator is disposed between an opposite second surface of the outer race of said bearing and the first shim, the first shim is disposed between the second isolator and the spanner nut. The first shim is provided with a member configured to be coupled to the housing to allow for axial movement but prevent rotational motion of the shim during installation of the spanner nut.
