Why is My Car Shaking?

If you notice your car shaking, vibrating or making any other movement out of the ordinary, it’s good to diagnose the problem early. Preventative and attentive maintenance will usually save you from bigger (and more expensive) repairs down the road. Even if the shaking is subtle, or it only occurs intermittently, don’t brush it off as something you can ignore. Here we go into detail about the different reasons behind shaking and vibrating.

There may be something wrong with your vehicle’s tires

  • Does your car start to shake around 50-55 miles per hour?
    • If this is happening, your vehicle’s tires probably require a tire balance.
  • Is the tire tread separated?
  • Do your tires show signs of uneven wear?
    • If this is the case, your tires probably require a tire rotation.

Your engine may not be getting enough air, fuel or spark to run smoothly

  • Does your car shudder or jerk when accelerating?
  • Does your vehicle feel like it’s on a highway ‘rumble strip’ when reaching 50 miles an hour?
  • Does your car start and drive as usual and begin to shake later into the drive?

These are all signs that you may need new spark plugs. If the plugs are in good shape, the actual spark plug wires could have a loose connection or need replacing. A dirty or clogged air filter could also be the culprit. Dirt could be cutting off the engines need of oxygen or fuel.

Your vehicle’s rotating parts could be damaged or need maintenance

  • Have you recently been in an accident or significant impact?
  • Does the shaking intensify as you drive faster?

You could have a bent axle or your driveshaft may need inspection. These constant parts transfer engine power to the rear axles and wheels in rear-wheel drive vehicles.

The rotors could be bent

  • Does your vehicle shake when you use your brakes?

If so, it’s likely that your rotors are damaged. The rotor is the shiny, silver disc-shaped component on vehicles with a disc brake system. If it’s used excessively, or there’s too much weight on it, it’s easy for it to become damaged. The calipers and brake pads, which squeeze the brake rotors to make the car stop, can’t get an even grip on a damaged rotor, which will create shaking.

Keep in mind these are just some of the reasons why your vehicle could be vibrating but are not the only possibilities. Virginia Tire & Auto recommends you bring your vehicle in for inspection for a proper and thorough evaluation.
