I think GM engineers, in their grand wisdom (?), anticipated the bushings and ball joints to wear about evenly (or the failure of one to necessitate the replacement of the other), so no real need to replace them independently. Both parts are replaceable, as we know, and the control arms almost always survive the bushing/joint wear. I've replaced both successfully, for years, without the aid of GM's repair manual advice or recommendation. GM shops and most shops that service suspension will not replace the joints, or bushings, with the only option being control arm replacement. It's a conspiracy, I tell ya.
