Why Does My Car Shake When I Accelerate
If you have an old car or the car hasn’t been adequately maintained, then your vehicle may rattle due to its age. However, some internal problems can also cause a car to shake.
You may feel your car shaking when you accelerate, and there are various reasons as to why this can happen. Usually, it’s a relatively simple reason as to why your car is shaking.
Sometimes though it can be a signal of a bigger problem, so it’s important to get your car checked out if you do feel it shaking. If you feel your car shaking, then you should take note of when it does shake. Does it shake when your driving at high speed? Does your vehicle shake at low speeds? Does your car only shake when you accelerate?
Here are some common reasons why your car may be shaking:
If you’ve recently had your tires replaced and your car has started shaking, then your new tires may be unbalanced. If your car shakes as your speed increases, then you should get your tires checked out.
If your steering wheel begins to shake at around 50 to 55 MPH and then increases at 60 to 65 MPH but then stops shaking at high-speeds, then you have unbalanced tires. Your vehicles width should be balanced evenly across the entire width of your tires, if this isn’t the case, then one side of the tire is carrying more weight than the other. This leads to uneven rotation, and since your tires cannot move the ground underneath them will ‘shake’ the body of your vehicle instead.
Loose Wheel Nuts
If the wheel nuts are loose on your car, then you may notice your car shaking. If the nuts are loose, then the wheel will not be held snugly against the hub of the vehicle. When you drive your vehicle, the wheels will shake.
The shaking will be felt in your steering and likely throughout the whole car. If you want to test whether your car nuts are loose, one easy way is to lift your vehicle with a floor jack on the side you suspect the nuts to be loose. Place your hands at the top and bottom of the wheel and try to rock it, if the wheel moves easily then the wheel nuts may be loose.
Worn Out Spark Plugs
If your car is accelerating slowly or is shaking when you do accelerate then your spark plugs may well be worn out. A spark plug is composed of materials that work together to produce a spark hot enough to ignite the air-fuel mixture. When these materials wear out, the spark plug will not be as effective as it could be. This can impact the rate your vehicle accelerates at, and it may be time for the spark plugs to be replaced.
