A solid friction coating is positioned within the interface. The solid friction coating is coupled to the inner surface of the ball race and/or the outer surface of the head portion of the ball stud. A piston can also be positioned within the cavity, wherein at least one gap is defined between the ball race and the piston and/or between the ball race and the housing. Methods of assembling a ball joint assembly are also disclosed.
