I'm on it thanks david...Next stop have the tires balanced
If they aren't balanced, they WILL shimmy, but the wheels and/or tires can still cause shimmies when they are balanced. They also have to be perfectly round and straight. You can balance and egg. It will still roll like an egg.
Like David said . . . ANYTHING that isn't just right in a Super's front end will have the same result . . . 45 - 55 MPH shimmies. Replace all of the joints, all of the bushings, the strut cartrides, steering u-joint shaft, steering damper and idler arm bushing . . . the steering gear box if it's got any play in it, put good true round tires on good round true rims and have them properly ballanced, install a strut tower brace for good measure, and have it lined up correctly . . . the result will be one of the best handling cars you've ever driven. At least until you hit a big pot hole.
