A base mounted lubricated ball joint utilizing a hollow socket case (20) is attached to an automobile axle or other workpiece by welding or bolting. A ball (42) is disposed within a socket (28) contained within the case and rotates freely within. A socket cap (52) is attached to the case leaving an upper portion of the ball (42) exposed, thereby permitting orbiting of the ball (42) upon its rotational axis limited only by its geometrical configuration. To utilize the invention, a shaft, a hydraulic cylinder, a table leg or a heavy machinery coupling is attached to the ball by threads. The ball joint is lubricated with grease through a grease fitting, which penetrate the joint and is distributed through grooves (36) located in both the ball and the case.
