ABSTRACT:
A ball joint includes a tubular outer shroud having a unique one-piece weld-free socket which receives a complementary ball of a tubular inner shroud. The ball joint is preferably formed by plastically deforming the outer shroud to integrally form the socket around the ball. The socket may be formed around a preformed ball, or both the ball and socket may be integrally plastically formed simultaneously.
