ABSTRACT:
A bore extends radially inward from the top side of the ball component of a ball and socket trailer hitch coupling and removably receives the stem projecting from the underside of a thin pad of plastic material having a low coefficient of friction, whereby when the socket component is coupled to the ball the pad is interposed between their confronting surfaces. The pad may be formed as a hollow segment of a sphere approximately matching the radius of the ball, or it may be flat but sufficiently flexible to be bent to conform to the spherical surface of the ball when the ball and socket components are coupled together.
