Message	:It's called the extension knuckle arm in the parts diagram. It's fastened to the steering knuckle through the kingpin and the steering knuckle is fastened to lower control arm through the lower ball joint. The tie rod holds the steering knuckle in place but the kingpin allows the vertical and the steering knuckles to pivot independently. The FUCA prevents the upright from pivoting on a vertical axis. With a single heim joint on the FUCA it looks like the upright will pivot changing the caster. Pivot with the center of rotation being the lower ball joint? With two opposing heim joints that could happen, but I don't see how it could happen with just one heim joint. Maybe I'm not following you... I had considered building a FUCA similar to this new design but I was going to use 2 heim joints side by side. I don't think that would work, because the FUCA not only articulates about the mounting point on the frame, but also articulates due to the arc movement imposed on the suspension by the tension rod. Maybe you could adjust one heim joint a bit differently than the other to account for the arc?
