I wish it were that simple for me. I've been through 3 RFBs, I RFB all my cars with any new tires or wheels. The 140s have multiple shimmy points in multiple areas, these threads are all over the place and I hate to get off topic, I hope OP checks all these areas. For me, everything mentioned has been ruled out except for the steering box, which I don't have much faith is resolving a shimmy issue. Curious how that component would be related to a shimmy.Roadforce balancing my Eltanins with Continental tires got rid of my shimmy issues. Before I did that, readjusting front wheel bearing freeplay made a big difference also. I still get shake for 5 miles after letting the car sit overnight, until they get themselves round again. I thought the tires might have some nylon plies, but they don't, so I'm not sure why they take such a "set".
