The bolt has some slop in the arm itself. I have new bushings also. I think it is worn from driving it with bad idler bushings. The arm could move up and down and we removed the bolt from the arm and it had play in it. It has more play in the arm then in the bushings actually. I am getting a used arm from a guy on th forum soon.
