ABSTRACT:
A method of manufacturing a ball joint serves to reduce the cost for producing the joint. In the method, while a ball portion of a ball stud of the ball joint is being placed in a mold, a socket is cast-molded in such a manner that the socket will form an integral structure surrounding the ball portion. Thereafter, force is applied to the outer wall of the socket by means of a plurality of mill rolls in such a manner that the force causes deformation of the socket so as to allow the ball portion of the ball stud to be slidably rotated relative to the socket.
