Whenever I drive my conv. @35-40mph, there is a noticeble shimmy in the front end. On smooth pavement, it feels like the wheels are moving from side to side. Sometimes, the tires feel like they are hopping. What does this indicate? Problems with ball joints? Tie Rod ends? o No: Something else entirely? Anybody have a diagnosis? Thanks David
If you have radial tires, you probably have shifted belts in one or more of them. One other possibility is a bent wheel. :bglasses:
Get the front end of the car completely off the ground. Then, with the steering unlocked, check for free play in the steering linkage. Try pushing both wheels in opposite directions, and in towards one another. Pay special attention to the idler arm. It bolts to the frame and one end of the centerlink. Grab the arm, and try to move it up and down. If you can, it's bad. It could also be tie rod ends, or any other part of the steering linkage.
You definitely have some looseness somewhere. Wheel balance usually shows up at speeds of around 50-75 mph. A loose u-joint will also make a vibration at the lower speed you described. :bglasses:
