  • Patent number: 11185914
    Abstract: 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.

  • Patent number: 11047465
    Abstract: A vehicle driveline component with a differential case, a cross-pin, a differential gearset, and a retaining member. The differential case is rotatable about a first axis and has an annular wall member that defines a differential cavity. The cross-pin is received in a cross-pin aperture formed through a first side of the annular wall member. The cross-pin extends through the differential cavity along a second axis that is perpendicular to the first axis. The differential gearset is received in the differential cavity and includes a pair of side gears, which are rotatable about the first axis, and a pair of pinion gears that are journally supported by the cross-pin and meshingly engaged with the side gears. The retaining member is welded to the annular wall member and limits movement of the cross-pin relative to the differential case along the second axis in a direction toward the retaining member.
