A rack and pinion steering apparatus  comprises a first bearing surface  that is formed on a surface that defines a passage in housing. An input assembly that includes a first portion of a control valve  extends into the passage of the housing . An output assembly  that includes a second portion  of the control valve is located in the passage of the housing . A second bearing surface is formed on an outer surface  of the output assembly . The first bearing surface cooperates with the second bearing surface  to define an annular space  for receiving fluid and for supporting rotation of the output assembly relative to the housing .
