Vibration in your car can be caused by a lot of different problems. Here are some of the most common reasons for the shaking in your car. These problems can get serious if left untreated, so make sure you get your car to an auto repair shop as soon as you can.
Problems with the engine
You engine can contribute to these symptoms if it is not getting enough fuel, air or spark. If you feel jerking during acceleration, shaking similar to that produced when going over rumble strips during driving in a specific range of speed or shaking after a period of operation, you may have problems with your engine. You may need to replace your spark plugs or check the spark plug wires for loose connections. A dirty air filter or fuel filter can also lead to these problems by limiting the supply of air or fuel.
Problems with the axle
A bent axle will result in jostling, especially at high speeds. Driveshafts can also be bent and result in shaking. CV joints that have worn out will also result in the same symptoms. Often, the boots of the drive axle joints can get torn and the dirt and dust that makes its way to the joint can cause damage and vibration.
Problems with brakes
If your shaking comes when you apply the brakes, you probably have a problem with the brakes. Warped brake rotors that result from overheating can lead to vibration. The brake pads will not be able to grab hold of the rotor and the car will begin to shake.
Problems with the wheels.
If you feel the vibration through the steering wheel, one of the most common causes will be misalignment of the wheels. Wheels may also have excessive play at the hub if it is not properly fastened with torqued long nuts. You may also need to replace the wheel bearings. There is also the problem of excessive runout which is when the wheel does not turn in a close to perfect circle when rolling. This can be remedied by replacing the wheel. Additional causes may be worn ball joints or tie-rod ends.
Problems with tires
Tires are one of the most common causes of shaking. There are several problems that can cause it- improper balance, separated treads, uneven tire wear and out of round tires. While some of these problems can be fixed by a rotation or balance, sometimes you may need to replace the tire.
An experienced auto repair mechanic can tell you what the problem is if you are unable to diagnose and fix it yourself.
