ABSTRACT:
A rack seal for use with a rack bushing and seal retainer wherein the rack bushing is made of a thermoplastic material and includes a face with a plurality of cooling cavities. The rack seal includes a body member, an annular sealing face, and a retainer air side which is in constant contact with the thermoplastic bushing cavity face. The rack seal air side surface includes a bead segment. The bead segment has a predetermined height which creates a minimum contact at a full gap with the rack bushing and is compressible to a minimum gap with the rack bushing. The bead segment of the rack seal is in constant contact with the thermoplastic bushing such that any objectionable noises are eliminated during any separation of the rack seal and the thermoplastic bushing.
