Today’s column, the reader has a Mazda 6 with questionable lower ball joints. Ray says to replace the ball joints you have to replace the entire control arm. It’s not possible to purchase only the ball joint.
Just curious, need a little Car Talk 101 education. Is this a common thing on newer cars? I’ve never replaced a ball joint, but I thought they were usually removable from the control arm, sort of bolted to the end of the control arm. So in most cases you could replace the ball joint and keep the same control arm. Like in this photo below. That triangular shaped thing at the bottom is the control arm, right? And above it, the rod-shaped thing is the tie rod end, right?
