Check Out These Top 4 Reasons Why Your Car is Shaking

November 9th, 2017 by

If your car is shaking, that’s a bad sign. You need to know why your car is rattling and shaking, and with that in mind, this list offers some of the more common reasons why your vehicle is bucking more than it should.

You’re on a Terrible Road

When your car is shaking, it’s easy to jump to conclusions and decide that the problem is inside your car and not underneath it. But if your vehicle always shakes the same way on the same part of your daily commute, it could be because of bumps in the road.

If the bumping and rattling only started recently, it could be a sign that a bad road got worse after a heavy rain or a sudden frost, creating new potholes. So if your car only seems to shake at certain times, try out a different road with the same weather conditions and see if your car still shakes.

The Wheels Are out of Alignment

Perfectly aligned tires give you the smoothest ride, but there’s some wiggle room where the alignment isn’t perfect but everything feels fine. But if you wait too long to have your tires rotated and balanced or if you bump into the curb one too many times, your front wheels will be so misaligned that each one will try to push the other to go the right direction. This doesn’t shake the car, but it does make the steering wheel vibrate, especially at high speeds. You can also get the same results from a bent axle, but that type of damage only results from a collision.

The Spark Plugs or Air Filter Are Going Bad

Sometimes the shaking comes from the engine, an off-balance noise and vibration that doesn’t match the way your engine normally behaves. As you probably suspect, this is a very bad sign. If the shaking is coming from the engine, there’s a good chance your cylinders are misfiring. There are a few different possible reasons, but the most common are failing spark plugs and a clogged air filter that can’t get enough oxygen to the engine.

The Brakes Are Failing

Disc brakes include a layer of tough, hard metal over a layer of softer metal. If you manage to wear through the hard metal, the car will start to shake as it hits the soft metal when you brake. The shaking may go away after a few minutes as the brakes warm up, but the problem is still there. You can also feel the same shaking if the brake pads are misaligned and start tapping the calipers. Either way, it’s time to get new brakes.

A shaking car can have a lot of causes. Sometimes it’s just the road, but there are times when the car shakes because something’s wrong. That’s why it’s important to understand how, when, and why your vehicle shakes: if you can figure that much out, you can usually learn how to fix the problem.
