Still driving my 2007 Lincoln Mark LT just turned over 137,000 miles. Have kept it in great shape. Taking it to the
Ford place tomorrow because it wants to "shimmy" (not front wheels) between 40-45 mph and then smooths out.
Just had 4 new Michelin tires put on on September 4.
Any ideas? Struts, spark plugs, transmission bands?
Just looking for some ideas.
Thanks.

New tires? A Wheel weight come off causing the vibration? --73.177.xxx.xx |

Ball joints tend to wear out along with front wheel bearings. Once up on hoist then can see all the worn suspension components. Ford tends to use lower quality parts which have to be replaced. As long as vehicle does not become a money pit then continue to repair. If front wheel drive then the front axles where the U joints out along with the rubber covers are torn. Once have the estimate then can determine if car is worthwhile. --147.194.xxx.xx |

Could be a driveshaft. I once had a rear wheel drive car and had the driveshaft professionally balanced and still had a vibration at certain speeds. I read an article in Popular Mechanics about a similar problem. I did as they suggested and knocked off the weights on the drive shaft and put two large clamps around the drive shaft with the screw part of the clamps close together. I would move the screw part of the clamps apart from each other a little and take a drive. After each drive I would move the weights some more. After 4-6 tries, I found the perfect balance and the clamps were still on the driveshaft when I sold the car around 10 years later. --99.165.xx.xxx |

Lots of possibilities. Struts, tie-rod ends, bent rim, lost a wheel weight. If it just started after the new tires then my bet is a wheel weight, bent rim, or they forgot to balance one or more of the tires. --64.130.xx.xxx |

Typically if you get a shimmy at a specified mph then it is simply tire balance. You just got new tires put on and so that is most likely it. You could have had a weight come off or a bead break in the old tires before you removed them which would have resulted in the same type of experience but most likely it would have been at a different speed just because it would be highly unlikely to be at the exact same speed but it could happen.
How long before you put the new tires on did this happen?
Did this start after hitting any potholes or anything?
What type of wear was on the tires? Unbalanced tires will typically cause cupping or waviness of the treads.
Unbalanced tires will vibrate or shimmy at certain speeds but will be smoother at other speeds. Other things that were mentioned, such as: shocks, struts, tie rod ends, u-joints, ect.... would usually cause constant vibration at all speeds and not smooth out that much at different speeds. These other problems would also cause different wear on the tires. If it were rotors that are warped or worn too thin(a common problem in modern vehicles) then you would get a bad shimmy when hitting the brakes. If it were u-joints on a front wheel drive(CV joints) then usually they would be popping when you make a sharp turn and typically do not cause vibration.

If you want to know if the problem is in the front or the rear then pay attention to were the vibration is felt. If you feel it in the steering wheel(which may not happen if you have electric steering) then it is the front wheels. If you feel it in the seat or seat back then it is in the rear wheels. If you feel it in the brake pedal then it is probably a rotor or brake pad problem or some other brake issue.
Your tire wear will tell you a lot about what is going on with your vehicle but if you have already disposed of your old tires and have new tires in place with no or very little miles on them then that is likely not an option.
I have a four wheel alignment checked every time I get new tires put on. It is best to have this done at the same time and after the new tires have JUST been put on. If the shop does the alignment properly then they will inspect the front end for worn and bad parts before doing the alignment. Always ask for a print out of the before and after alignment. Like your rentals, keep a folder and records. --73.120.xx.xxx |

wheel balance maybe but I am getting intuition that something right near the tire and axle is breaking and it could break while you are driving. let me know as the wheel could come off. In my old VW there was something up front that needed replacement. Wish I could remember what it was called. --71.104.xx.xxx |
