A method for forming an assembly having a housing and first and second components. The first and second components are movable relative to one another in the housing. The method includes: providing first and second workpieces; moving the first and second workpieces relative to one another in a predetermined manner that produces relative sliding contact between the first and second workpieces while performing a superfinishing operation on the first and second workpieces to form the first and second components, respectively, wherein the superfinishing operation does not comprise a lapping operation; and mounting the first and second components in the housing such that the first and second components are engaged to one another and are movable relative to one another in the predetermined manner.
