Quora also offers a range of community insights and personal experiences in “How to fix a car that is shaking while driving at slow speeds”.

Unbalanced Tires

The term “unbalanced tires” might sound like heavy mechanic lingo, but it’s actually quite simple! When we’re talking about car shaking, one of the first culprits you should keep an eye on is your tires.

An unbalanced tire means the weight is not evenly distributed across the tire-tread surface. This can make your car’s ride rough and cause it to vibrate at faster speeds, or when you hit certain types of road surfaces like potholes or pavement seams. Uneven tire wear compounds this issue over time, gradually leading to a persistent shake.

Tires come balanced from the factory, but driving conditions, potholes, and normal wear and tear can cause them to lose this balance. If you’ve recently started noticing a shake, especially at speeds from 50 to 70 mph, then your tires could be the issue.

Checking for unbalanced tires isn’t a complex process. You can conduct a simple experiment: drive your car on a flat, straight section of road at different speeds. If the shake becomes noticeable at a particular speed and then disappears as you accelerate or decelerate, then it’s likely that your tires need balancing.

Getting your tires balanced involves placing them on a specialized machine that spins them to find the heaviest areas. These heavy spots are then compensated for with weights that the mechanic will attach to the wheel. Regular tire rotation and maintenance can prevent unbalancing and increase the life of your tires.

To sum, if your car has been shaking and you’re seeking answers, unbalanced tires could be the cause you’re looking for. But remember, it’s always best to get a professional opinion, as routine maintenance is key to optimal performance. So, if you’re unsure, have a trusted mechanic take a look. Stay on course with us as we steer you through more potential reasons behind your car’s unwanted shakes.

Worn Out Brake Pads

As you dig deeper into the reasons behind your car’s shaking, Worn Out Brake Pads may surprise you as a common culprit. This scenario typically arises if you use your brakes frequently or simply when you’ve been driving your car for some time.

Ever noticed that distinct squeaking sound when you step on the brake? That’s usually not just annoying noise, it’s actually the warning signal your car is giving you. While the materials used in brake pads are designed to handle heat and friction, they inevitably wear down with repeated use and time.

Listen carefully. If the squeaking turns to a grinding noise, it signifies an even more urgent issue. It’s a clear hallmark that your brake pads are seriously worn out and your car’s disc and caliper are directly rubbing against each other. That’s a cue for immediate action as it may not only cause vibrations but can also lead to more serious damage or even brake failure.

What does this mean for your ride? The worn out brake pads essentially make it hard for your car to maintain a smooth ride, especially when trying to slow down or stop. This potentially results in vibrations that you can feel through your steering wheel. Remember, your safety while driving is paramount, and something as simple as replacing worn out brake pads can make a significant difference.

Do yourself a favor. Don’t try to stretch the life of those brake pads. If you’re dealing with serious wear and tear, it’s time to replace them. Though it may seem as an additional expense now, consider it an investment in your car’s future. Not to mention, the peace of mind it gives knowing you’re ensuring your vehicle’s peak performance.

For this, there’s no better solution than relying on a trusted professional. Be it for a regular check or brake pad replacement, consult a technician. They’re equipped with the right tools and knowledge, ensuring that your brake system will function at its best.

So, the next time you hear a strange sound from your brakes or feel your car shaking, take a moment to think about those precious brake pads. A prompt check and proactive maintenance could save you more than just a bumpy ride.

Engine Misfiring

Another driving factor behind your car’s shaking could be Engine Misfiring. This happens when one of the engine’s cylinders fails to function correctly, resulting in an imbalance in the engine’s rhythm. This imbalance is the precise cause of the unnerving vibrations you feel when you’re behind the wheel, accelerating, or even idling at a traffic light.

Misfiring can occur due to several reasons, such as:

  • Faulty or worn out spark plugs
  • Ignition coil issues
  • Fuel injector problems
  • Incorrect fuel/air mixture
  • Timing belt wear and tear

When your engine misfires, the car doesn’t run as efficiently as it should. Fuel consumption increases, exhaust emissions go up, and your car might not be as responsive or powerful as you’re accustomed to.

Faulty or worn out spark plugs, being a typical culprit, deserve special attention. These small yet vital components are responsible for igniting the fuel in your engine. When they fail or wear out, they can’t generate an adequate spark, leading to your engine’s misfire and subsequent shaking. If you notice a decrease in your car’s acceleration or your fuel economy’s gone down, it’s time to inspect the spark plugs and possibly, replace them.

However, you want to address an engine misfire as quickly as possible. Prolonged misfiring can cause extensive damage to your car’s engine and exhaust system. Ignoring these warning signs equates to risking the need for costly repairs down the line.

So, keep a keen ear out for unusual engine noises, and be vigilant about any noticeable changes in your car’s performance. If something doesn’t feel right, trust your instincts—it’s always better to get a professional diagnosis and nip the problem in the bud.

Remember, regular car maintenance is key to preventing engine misfires—ensure regular service and promptly address any issues you encounter. A smooth, shake-free ride is well within your grasp when you take proper care of your car.

Suspension Issues

Another common culprit behind your car’s shaking might be problems with its suspension. The suspension system in your car is critical. It connects your vehicle to its wheels and aids in providing a smooth ride, even on rough terrain. Issues with this system may often lead to noticeable vibrations during your drive.

Faulty suspension components, such as worn-out shock absorbers or struts, can cause your car to shake. The function of these components is to manage the impact and rebound movement of your car’s springs and suspension. Over time, these parts wear out, disrupting the smooth ride you’re accustomed to.

Furthermore, damaged steering and suspension components can lead to your car shaking. Uneven tire wear is an indicator of this type of problem. Regular tire rotations and alignments can prevent this issue, emphasizing the importance of consistent car maintenance.

If you notice a vibration that seems to intensify as you gain speed, irregularities in your car’s wheel balance could be the culprit. Improper wheel balance can strain your suspension, ultimately causing your car to shake. To alleviate this issue, it’s advised to have your wheels balanced every 5,000 to 6,000 miles.

It’s impossible to avoid every bit of rough road or every pothole, but some shocks and suspension system damage comes from impact with these obstacles. You can’t align, balance, or rotate your way out of that kind of problem. In such cases, the damaged parts must be replaced.

Don’t rule out the role your suspension system plays when troubleshooting your car’s vibrations. Ignoring these issues will not only lead to an uncomfortable ride but can also cause long-term and potentially expensive damage to your vehicle. Always consult with a professional if you suspect suspension issues, and ensure your car gets its regular maintenance check-ups. The smooth, shake-free ride you’ll achieve is worth it.


So, it’s clear that a shaking car can be a sign of several issues, particularly with the suspension system. Faulty shock absorbers, struts, or damaged steering components can all lead to this uncomfortable situation. Regular tire rotations, alignments, and wheel balancing are crucial for keeping your ride smooth and shake-free. Remember, any damage from road impacts may need part replacements, so don’t ignore the signs. To prevent discomfort and potential long-term damage, it’s best to address suspension problems promptly. Consult with professionals and maintain regular checks for a smooth, shake-free driving experience. Your car’s health is in your hands. Be proactive and keep your ride as smooth as possible.
