The automobile industry has come a long way, and modern cars are designed for a smooth drive. any nuisance, such as vibration or shaking during the drive, is not considered normal. It is usually an indication that there is some wrong with your vehicle and needs immediate attention. The reason can be anything from the vehicle’s worn tyres, wheel alignment, suspension or brake issues. If you experience excessive or continuous vibration during driving, read on to find out possible car shaking reasons.
Common Car Shaking Reasons
If you are wondering why is my car shaking while driving, then check out the following reasons. These are some of the most common reasons why a car shakes when driving.
Wheel Imbalance
When a tyre is imbalanced, its weight and wheel assembly are not distributed evenly around the car axle. Due to this, a tyre can spin unevenly and create vibrations that are transmitted through the suspension. Several factors can lead to wheel imbalance, such as uneven tyre wear and incorrect pressure. You can always use different types of tyre pressure gauges to check if your car tyres are overinflated or underinflated.
When the tyre rotates, the heavier part will move to the bottom, creating a shaking or vibrating effect. This makes your car shake when braking at high speeds, making the ride uncomfortable and potentially dangerous.
Brake problems
Several car brake problems cause a car to vibrate. Some of the most common causes of brake-related shaking include:
- Sticking brake callipers: Sticking or malfunctioning brake callipers may cause uneven pressure to the brake rotors, which ultimately vibrates the car.
- Out-of-round brake drums: If the brake drums are out-of-round, they can cause the brake shoes to make uneven contact with the drum and give a shaking feeling when you apply brakes.
- Warped brake rotors: Due to excessive heat or uneven wear, brake rotors can become warped over time. If the rotors are warped, they will cause vibrations once you apply the brakes. Make sure to get your brake rotors replaced immediately to avoid car shaking issues.
- Worn brake pads: A bad brake pad worn down to its metal backing plates can cause rhythmic pulsing or shaking due to metal-on-metal contact. This is why your car brakes must be repaired or replaced if found worn.
Engine misfires
An engine surge is one of the reasons why a car shakes when driving. It occurs when one or more cylinders in an internal car combustion engine fail to fire properly. This results in a loss of power and an irregular engine rhythm. Engine misfires can cause a car to shake or vibrate due to several reasons. Some of them are:
- Ignition system problems: If the ignition system is not functioning properly, it can cause a misfire in one or more cylinders, resulting in shaking and vibration.
- Vacuum leaks: Vacuum leaks in the intake system can cause an engine to misfire, which leads to shaking and vibration.
- Worn or damaged engine components: Worn or damaged components, such as spark plugs, spark plug wires, or ignition coils, can also cause an engine to misfire and make your car vibrate while driving. Besides, faulty spark plugs are one of the reasons why the car shakes when starting.
Tyre problems
Worn tyres can cause a car to shake for several reasons:
- Uneven tread wear: Tyre treads can wear down unevenly with time and create a condition known as cupping. When the tyre rotates, the uneven tread can cause it to bounce and make your car shake.
- Poor tyre quality: Low-quality or damaged tyres can also cause shaking and vibrations in the car. This can be due to various factors, such as manufacturing defects, cuts, or punctures in the tyre.
To avoid any such situation, make sure you have a spare tyre with you. Driving with worn-out tyres can be dangerous, as it can affect handling, braking, and stability, as well as increase the risk of a blowout or puncture. Hence, change the car tyre after 5 years of its purchase.
Worn suspension parts and joints
The car suspension’s components like struts, shocks and control arm bushings are designed to absorb the bumps and vibrations from the road, but over time they can wear out or become damaged, reducing their effectiveness.
If the suspension components are worn or damaged, they can no longer effectively control the movements of the wheels and suspension, leading to excessive vibrations and shaking in the vehicle.
Loose or damaged steering component
Damaged steering components can cause a car to shake for several reasons:
- Loose steering wheel: Loose steering wheel of a car can cause it to shake, especially at higher speeds.
- Worn or damaged ball joints: Ball joints are the pivots between the control arms and the steering knuckles that allow the wheels to turn. If they’re worn or damaged, they can cause the front end of the car to shake, especially during turns.
- Worn or damaged tie rod ends: Tie rod ends are the components that connect the steering gear to the wheels and transmit the steering inputs from the steering wheel to the wheels. If they’re worn or damaged, they can cause the car to shake, especially during turns.
- Loose or damaged suspension components: If the suspension components, such as struts, shocks, or control arm bushings, are loose or damaged, they can cause the car to shake, especially over rough roads.
These are some of the common car shaking reasons. If you’re experiencing car shaking due to any mentioned issues, it’s important to have a professional diagnosis and repair to ensure your safety. Driving with loose or damaged car parts can be dangerous, as it can affect the handling, stability, braking performance and other issues.
