The first annular portion has a first mating surface that defines a first opening having a first diameter, the second annular portion defines a second opening having a second diameter that is smaller than the first diameter, and the intermediate portion defines a shoulder. The inner member includes a generally radially extending portion having a generally axially facing surface and a second mating surface that is engageable with the first mating surface to interlock the inner and outer members together. When the inner member is mounted on the outer member, the radially extending portion extends into the first opening, and the generally axially facing surface engages the shoulder.
