ABSTRACT:
A method for connecting a ball and socket joint to a control arm in a vehicle suspension system includes providing the ball and socket joint with a socket portion having a circumferential flange. The ball and socket joint is initially aligned with an opening formed through an outer portion of the control arm. Then, the ball and socket joint is moved upwardly such that the socket portion is received within the opening. The socket portion defines an outer diameter that is preferably slightly smaller than an inner diameter defined by the opening formed through the outer portion of the lower control arm. However, the flange defines an outer diameter that is preferably larger than an inner diameter defined by that opening. Thus, the engagement of the flange with the lower surface of the outer portion positively positions the ball and socket joint relative to the lower control arm. Then, one or more regions of the socket portion of the ball and socket joint are deformed into engagement with the upper surface of the outer portion of the lower control arm. The deformed regions cooperate with the flange to trap the corresponding portions of the outer portion of the lower control arm therebetween. As a result, the ball and socket joint is securely connected to the lower control arm.
