Reasons why a car shakes while driving

How would you feel if your car shakes while driving? Both uncomfortable and hazardous, a vibrating steering wheel or cabin might occur. These types of vibrations are indicators of an automobile issue that has to be fixed for comfort and safety on the road.

For seasoned drivers, evaluating and determining the causes of a vibrating car is simple. For newbies, it will be difficult, especially if they encounter automobile trembling at high speeds. Beginners should get their automobile fixed as soon as they feel a vibration in order to prevent damage to other car parts.

There are numerous factors that may contribute to the car vibrating. Thus, in this article, we’ll be discussing the reasons why a car shakes while driving.

So, let’s dive in!


Reasons why a car shakes while driving

Faulty brakes

Since the front brakes of your automobile experience the most stress when you apply the brakes, if vibration happens when doing so, the issue is probably with the front brake mechanism. The pads and rotors are two components on the front disc brakes that require periodic replacement. The cylindrical metal disc that is attached to the wheel is called a rotor. Due to extensive use and abuse, it may get distorted over time.

In order to slow down the car, pads are pressed up against the rotor, and for the pads to function effectively, they must be a specific thickness. The vehicle may vibrate if the brake pads are overly worn. The caliper aids in slowing and stopping the car by applying pressure to the brake pads against the rotor. Timing for replacing brakes varies across all vehicles. They ought to be changed about every 50,000 miles on average, although many makes and models can survive much longer.

The owner’s manual for your car can provide a more precise replacement schedule. Additionally, ask your mechanic to visually inspect the state of your brake pads and rotors each time you get your oil changed. These experts can help you determine when replacement is required.

Wheel and tire problems

Wheel or tire issues are the most common reason for vibration. Uneven tire wear, split tire tread, out-of-round tires, broken wheels, and even loose lug nuts are examples of potential issues.

By doing regular car inspections, such as visually inspecting the wheels and tires, testing and changing tire pressure, and gauging lug nut tightness, many of these problems can be prevented. Tire rotation, balance, and optimum tire pressure should all be part of your routine maintenance regimen. Additionally, wheel alignment should be done on a regular basis.

Engine and transmission problems

A few components in an automobile’s engine have the potential to shake the car if they break down. These include the engine air filter and spark plugs. Examine the connections and spark plugs. Spark plugs typically last between 80,000 and 100,000 miles, depending on the make and model of your car. Check your air filter next if the spark plugs are functioning properly and their connections are secure. The engine may be deprived of the oxygen and/or fuel it needs to function efficiently if the engine air filter is unclean or clogged.

A damaged radiator fan or even an engine or transmission mount could be to blame. A broken fan will typically be unbalanced and rotate with a noticeable vibration. However, the majority of automobiles feature electrically driven radiator fans that only turn on when the coolant temperature rises above a specific point. The fan may be the culprit if your vibration is irregular and only occurs after the engine is warmed up, although this is highly unlikely.

Axle problems

The majority of vehicles have two axles, one connecting the front wheels and the other to the back wheels. Vibration can arise if either axle is twisted or dented, which can happen in an accident or other mishap with the road. If the problem is with the axle, the vibration will typically get worse as you accelerate. Check for potential issues with the driveshaft and CV joints as well. If the CV joints are worn, dust and other debris may enter, endangering the joints.

Worn suspension parts and joints

Your steering wheel may tremble due to looseness in the suspension or steering system components. Your car can’t be correctly aligned if its tie rod ends or ball joints are too worn. Have a mechanic examine your ball joints and other parts of your car so they can determine what is causing your steering wheel to wobble.

Worn spark plug

Your engine’s piston firing order will be altered if your spark plugs are past their prime. With each firing cycle, the engine may tremble as a result of this new firing order’s potential for misfires. The fix should be an easy spark plug replacement. Check your fuel and air filters if necessary.

Spark plugs may become deficient in either of the components necessary for combustion due to a clogged air or fuel filter. Engine trembling and misfires are also caused by a lack of air or fuel. Your Check Engine Light will turn on as a result.

Is it okay to drive a car while shaking?

It is best to address the issue straight away before continuing to drive if your automobile starts to shake frequently. Driving through the shaking might cause more damage to the vehicle, break the tires, and cause other expensive issues that could be prevented with a short visit to the repair.

How do I fix my car from shaking when I drive?

  • Do a wheel balance.
  • Get loose lug nuts tightened.

Should I be worried if my car is shaking?

No matter what is causing your automobile to shake, it’s critical to not ignore it and have it examined as soon as you can. Even though it might only be a small problem, ignoring it could cause more serious issues and expensive repairs in the future.

Can spark plugs cause the car to shake?

Inefficiently working spark plugs result in an uneven fuel burn in the engine, causing the RPMs to fluctuate and the noise to get louder. Additionally, while idling or moving at a slow speed, your vehicle may vibrate more intensely. The entire car may shake as a result of these vibrations, which come from the engine.

What causes the car engine to shake?

A petrol automobile’s engine may misfire in one or more cylinders due to worn or dirty spark plugs, which may result in vibrations while the car is idling or moving at a pace. The simplest fix is to change your spark plugs and inspect the associated wiring. The air and fuel systems may also be to blame for engine vibrations.

Can low oil cause a car to shake?

In any case, it would be wise to get your car looked at in this situation. If your automobile rattles when it is idle, you may need to change the oil. This is due to the increased friction that a lack of oil will generate in your car’s engine.

Why does my car feel bumpy when I drive slowly?

Rough, bumpy rides can be caused by improper tire mounting, poor tire alignment, and wrong air pressure (too low, too high, or different pressures in each tire). The worst-case situation might be that the rims have sustained damage or are bent.
