Why Is My Car Shaking?

Cars sometimes feel or sound strange when something's wrong. Shaking is one symptom a vehicle produces when there's a problem with certain parts. Shaking may be accompanied by other symptoms, too, depending on where the issue originates. While there are multiple possible reasons for the shaking or vibrating sensations you're experiencing with your vehicle, only an expert mechanic can diagnose the underlying issue and make repairs.

Engine

Shaking caused by engine problems may be first apparent when you turn on the car. It can also continue even as you drive. Several underlying issues may be responsible. The engine relies on the engine air filter to produce clean, fresh air to work properly. If dirt, debris, or other materials contaminate the air filter, it doesn't let enough air get to the engine, which then causes the engine's efficiency to become reduced. The engine also has a few components that may cause the car to shake if they're experiencing problems. The spark plugs, which help the engine send fuel through the gas lines, may need to be checked between the 80,000-mile and 100,000-mile mark. The engine's radiator can also break and lead to shaking.

Brakes

Worn brakes are another possible cause of your car's excess shaking or vibration. Most brakes have an average lifespan of about 45,000 to 50,000 miles. However, they may need to be checked more frequently if you are heavy on the brakes or frequently drive in stop-and-go traffic. If the brakes are causing the shaking, the problem likely stems from warped brake rotors or worn-out brake pads. The pads are sandwiched in between the rotors and generally keep them from hitting. However, the brakes can lead to shaking if the protective padding is worn out.

Tires

Tire problems may also be the source of your vehicle's excess shaking. Tires should be kept within a certain tread depth range for safety reasons and to prevent other problems. The car might start shaking because the tread levels on the tires are below their recommended minimum range. Uneven wear or abnormal tire pressure ratings might also explain why your car is shaking.

Wheels

If the wheels on your car get dented, such as from an accident or other impact, they might be the cause of your vehicle's shaking and vibrating. Additionally, the ball joints, wheel bearings, and other parts may go bad. The steering wheel may feel wobbly, or the handling might feel loose if the wheels are causing the issue.

Axles

Similarly, one or both axles on your car can start creating vibrations if they are damaged. They also have parts called CV joints that can get contaminated as they wear out, which allows dirt and other debris to damage the joints and keep the axles from functioning correctly.
