By just loosening the nuts 1/4 turn that totally freed it up and everything was silky smooth. Maybe the bearing surface on the outer hinge pin could be a half mm longer so if you bottom out the nut on the shoulder of the pin it doesn't squeeze the arm and make it bind. No issue with turning the nut out a little. It works and shouldn't come loose.
Yes, the nutted outer hinge pin has to be able to spin by hand. If the nuts are too tight, it will severely bind the suspension. We have since fixed the outer hinge pins so in time, that wont be an issue.
