A rack drive assembly adapted for use in a vehicle electric power steering assembly includes a bearing assembly disposed in a rack housing and carried by a ball nut assembly for rotatably supporting the ball nut assembly relative to a steering member; and a spanner nut carried by the rack housing for securing the bearing assembly in the rack housing. 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.

An apparatus (,) includes a hydraulic fluid power cylinder (,) and a steering rack (,). The rack (,) is fixed to a piston (,) in the power cylinder (,), and extends outward through an open end (,) of the power cylinder (,). An annular hydraulic fluid seal (,) is received over the rack (,) in dynamic sealing contact with the rack (,). The seal (,) defines a fixed end of a variable volume hydraulic fluid chamber (,) extending from the piston (,) to the seal (,). The apparatus (,) further includes a housing part (,) which is mounted on the power cylinder (,). The housing part (,) supports the seal (,) at a location spaced outward from the open end (,) of the power cylinder (,). In this arrangement, the housing part (,) defines an end section (,) of the fluid chamber (,) extending outward from the open end (,) of the power cylinder (,) to the seal (,).
