Have your tires checked, you probably have a shifted belt in one or more of the tires.

It is most likely the tires. Change the tires and the vibration will disappear. J.

SOURCE: there is a vibration and loud hum that occurs

These symptoms are also consistent with a bad wheel bearing.

There are several things to consider, first I would check the tire balance. Then I would go to the front alignment. If you have trouble on one side or the other you may just have a bad tire.

There are many stages of vibration. The most common is in the steering and USUALLY a steering dampner will correct this. However, your description is not real defined and until the technician actually experiences it, it cannot be properly diagnosed

I have a 1999 ford f 350 7.3 diesel. it drives ok but at 40 mph it vibrates pretty bad but at 45 it goes away but with a minor shake....and when i stop it vibrates i figure its the brakes being warped is...


could be out of balanced tires or possibly your suspension could be out of alignment, brake rotors being warped will only cause a vibration when pressing the brakes

Buick lesabre starts vibrating at 45 mph and stops around 55 mph...the steering wheel does not shake much but you can feel it vibrating just the same.....had new tires put on and balanced for the 2nd...


A vibration such as you are talking about could be caused by more then one thing. First it could be caused by a broken belt in one of your tires. I could also be caused by a bent rim, a warped rotter, or a bad cv joint. I hope this helps you solve your problem.

Vibration


Is the vibration all around the car ......or steering wheel.....or any other particular part?......If it is all around then I am more inclined to believe that it has something to do with spark plugs and or wires....check them out and replace as needed...Another thing that it could be is your air filter ...it may need to be cleaned or replaced. It could also be that you have warped rotors....they will cause vibration while driving ....but problem is most apparent when braking.
