it all depends on the suspension or the tires I know for a fact that a bad tire could make the vehicle shake if its warped or out of round or it could be out of balanced or in need of a wheel alignment it just depends on the situation at the time I advise you to check were its coming from either front or back check the tires and the wheels for bent wheels or damaged tires jack the front end of the vehicle and put your hand on the wheels top to bottom if loose check lower control arms and struts then put your hands on the wheel side to side and if it shakes or have play that's another problem
If your car shakes only when your going a certain speed, it is most likely resonance. Which means your wheel weights are off, or maybe you dont have any. But if it always shakes, it could be a bent rim. The final option, is something else, it could be many different things
road V.A
You have a wheel out of balance more than likely.
it sounds like your timing may be off
tires need to be balanced or you have a bent rim or a broken belt in your tire
Wheels need to be balanced, especially if shaking increases with speed..Tom.
Warped brake rotors/drums.
Could be a tire or wheel that is out of balance Could be a bad tire with internal damage Could need a new car
The average speed of any car should be the posted speed limit.
Shaking in any car can be a number of different things.eg suspension components worn,steering worn,wheels bent,axles bent etc etc.Try to be more specific on when your car actually begins to shake.ie:certain speed,cornering etc.
It is probably missing. Have it tuned up and a compression test run on the engine.
If your car shakes while underway, your tires have worn incorrectly from misalignment. If it shakes while in park or not moving, your engine is misfiring.
