Tom, looking at the video again I see what you mean about the arms moving on the bushings. The springs appear to be pushing against the bushings. Do the other arms move on their bushings or do the arm-bushings assemblies move on the shaft? I would think that the bushings outside would be a press fit into the arms, the bushings inside fit to the shafts so as to allow rotating movement, and the bushing and the arm assembly rotate on the shaft. If this is correct, then the bushings on the two in question have come free of the arms allowing the arms to move laterally. It is hard to trouble shoot from a distance, but I believe this is what is happening. Stay cool - John
