Abstract
A ball socket member open at one end is formed of yieldable semi-rigid plastic material, with external ears and internal axially extending lubrication distribution and relief slots positioned in alignment with the ears. The slots terminate at the open edge, the lubricant being retained by a closed cell seal of cellular material. An external circumferential groove receives the periphery of an opening in a linkage member, the external ears being received in key slots in the opening. The periphery of the opening is deformed out of the plane of the surface of the linkage to produce an effective thickness approximately the thickness of the groove, providing a method and construction to assure a secure fit in cases where the thickness of the linkage material is either greater than or less than the width of the groove.
