Abstract
A pivot socket includes a housing with an inner surface providing a cavity extending between a substantially closed end and an open end. A cartridge bearing is received in the cavity with a spring disposed between the closed end and the cartridge bearing. The cartridge bearing has an inner surface with a cylindrical portion and conical portion converging inwardly from the cylindrical portion. The cylindrical portion houses a tapered bearing for relative axial movement therewith. A stud having opposite first and second tapered surfaces diverging away from one another is received in the cartridge bearing, with the first tapered surface engaging the tapered bearing for relative sliding movement therewith and the second tapered surface engaging the conical portion of the cartridge bearing for relative sliding movement therewith, thereby causing the relative axial movement between the tapered bearing and the cartridge bearing.
