Right, but the bushings are held on by a bolt and nut. When I got my new ones they could be laid down flat, the bushings would swing freely because the bolt and nut wasn't tightened down yet. When I removed the old one, the bushings were tight, in an "L" shape.

Do I tighten 15 and 17 after the new arm is installed and the weight of the suspension is on it. I'm talking really crank on the bolt and nut so it tightens in on the bushings? Or do I leave it free swinging?
