Abstract: A ball joint assembly for a vehicle suspension includes a control arm configured to connect to or engage a frame of a vehicle, a ball, a taper connected to the ball, the taper configured to connect to or engage a steering knuckle that connects to a wheel of the vehicle, and/or a housing comprising an adapter system configured to connect to the control arm. The ball at least partially in the housing with grease at least partially between the ball and the housing. The housing, the ball, and the taper are configured for the housing and the ball to articulate relative to each other to provide a predetermined angularity of movement in all 360 degrees of orientation with a predetermined minimum pullout force in all 360 degrees of orientation.

Abstract: Ball joints can be greased, serviced, and sealed from the environment. The ball joints can be retrofitted as an aftermarket part. The ball joints can be retrofitted into certain control arms, such as aftermarket tubular, formed steel, or billet aluminum control arms used for off-roading and other extreme sports. The ball joints can provide a predetermined angularity of movement desirable in, for example, off-roading and other extreme sports. The predetermined angularity of movement can be high or wide relative to the angularity of movement or displacement provided by standard or factory ball joints.
