I asked this question a couple of days ago but didn't get any good answers. I have a 2005 Ford Taurus. There is a "shimmy" in the front right wheel. It mostly happens at 60-75 mph but can happen at any speed at different times. It doesn't get worse when I apply the brakes. It is destroying my tire and brakes on the front right only. Here's what has been fixed so far-wheels have been balanced and rotated, alignment checked, new tire, new axle, new rotor, new front brake pads. Caliper is okay. Two ASE certified mechanics can't figure it out. Any suggestions? They want me to keep throwing money at it. I have already spent over $1000 and the problem hasn't gone away at all.

Hi Gang, I have a 2005 Ford Taurus. There is a "shimmy" in the right front wheel. It only happens at a certain speed and the speed that it happens at changes depending on how far I have driven that day. The alignment is okay, the balance is okay, I have rotated the tires, and the brakes have been changed. Sadly, the front right tire and the front right brake go bad every 10,000 miles or so-so I have to keep changing them, but the tires and brakes on the rest of the car are fine. The car has never been wrecked. The mechanic that looked at it is stumped (although I don't think he's that great of a mechanic anyway.) Any suggestions?

This is a good question for Civil Engineers. When I'm driving, I see a lot of signs that state "6% grade ahead". Obviously that means you're going uphill or downhill but is there a formula for actually calculating what the grade is?
