Patent abstract
A bushing for use in a hollow tube housing of a rack and pinion steering system. The bushing is formed as a generally cylindrical body having a central aperture and a circular cantilevered flange that extends outward from the body of the bushing. The flange contains a leading surface for compression contact with a corresponding interfering surface on the hollow interior of the rack housing. The flange is disposed to continuously compress a portion of its leading surface against a portion of the interfering surface on the hollow interior of the housing over a predetermined range of temperatures when the bushing is installed in the housing, and thereby providing thermal compensation to maintain a seal.
