How to Repair a Car That Shakes When Driving at High Speeds
1. Understanding Why Your Car Shakes at High Speeds
One of the most frustrating and concerning experiences I’ve had with my car was when it started shaking at high speeds. The first time it happened, I thought something was terribly wrong with the engine, or worse, I was having a mechanical failure that would leave me stranded on the side of the road. But after taking the car in for a check-up, I realized that car shaking at high speeds is actually a relatively common issue, and in most cases, it can be repaired without too much hassle.
Vibrations when driving at high speeds typically signal that something isn’t quite right with the vehicle’s wheels or suspension. These shakes can range from subtle vibrations to full-on shaking, and they often become more pronounced the faster you go. It’s important to recognize the cause early on to avoid any more serious problems down the road. Let me walk you through what I learned and what I did to fix it.
2. Common Causes of Car Shaking at High Speeds
After some research and talking to my mechanic, I discovered that there are a few common culprits behind the shaking. In most cases, it comes down to issues with the tires, wheels, or suspension system. Here's a breakdown of the most common causes:

2.1 Tire Issues
One of the most frequent causes of shaking at high speeds is uneven or worn-out tires. When tires lose their balance or develop flat spots, they can create uneven contact with the road. This unevenness results in vibrations that can be felt through the steering wheel or the car body. Over time, these issues can become more pronounced, making your ride uncomfortable and even unsafe.

2.2 Wheel Alignment Problems
Improper wheel alignment can cause the car to pull in one direction while driving at high speeds, which leads to vibrations. Misalignment often occurs after hitting a pothole, curb, or in the case of general wear and tear. When your wheels are not aligned correctly, they’re not in their optimal position to roll smoothly, which leads to vibrations at higher speeds.
2.3 Unbalanced Wheels
If your wheels are not properly balanced, they can also cause the car to shake at high speeds. A wheel imbalance means that the weight of the wheel and tire assembly is not distributed evenly, leading to vibrations when the car reaches higher speeds. This is another issue that can become worse over time if not addressed promptly.
2.4 Suspension Problems
Your car’s suspension system is designed to keep the vehicle stable and absorb shocks. If any of the suspension components, like shocks or struts, are damaged or worn, it can lead to poor handling and shaking, particularly at higher speeds. Worn suspension parts can cause the car to feel bouncy or unstable, which is most noticeable when driving at higher velocities.
2.5 Brake Issues
Though this one is less common, warped brake rotors can also cause shaking, especially when you press the brake pedal. If the rotors are warped or worn unevenly, it can create vibrations when driving, particularly at high speeds when braking is applied. This is often felt as a pulsing or shaking sensation in the steering wheel or pedal.
3. Steps I Took to Fix My Car That Shakes at High Speeds
Once I understood the potential causes of the issue, it was time to fix it. Here’s how I went about addressing the shaking in my own car:
3.1 Checking the Tires
The first thing I did was take a close look at the tires. I inspected them for signs of wear, including bald spots, cracks, or any objects stuck in the tread. I noticed one tire was slightly worn on the outer edges. This could have been the cause of the imbalance and uneven contact with the road.
Next, I took the car to a mechanic who performed a tire balance check and rotated them. Balancing the tires ensured that the weight was distributed evenly across the wheels, which fixed the vibrations I was feeling at high speeds.
3.2 Getting a Wheel Alignment
After the tire balancing, I had the mechanic check the wheel alignment. Sure enough, my car was slightly out of alignment, which was contributing to the shaking. After they realigned the wheels, the car handled much better, and the vibrations at high speeds decreased significantly.
3.3 Inspecting the Suspension
Next up was the suspension. My mechanic took a look at the struts, shocks, and other suspension components. Luckily, everything seemed to be in decent shape. However, if your suspension system is showing signs of wear, replacing the shocks or struts can help restore stability and reduce vibrations.
3.4 Checking the Brakes
Finally, I had the brake rotors inspected. In some cases, warped rotors can cause shaking, especially when braking at high speeds. Fortunately, mine were fine, but if this were an issue for you, replacing the warped rotors would be necessary.
4. When to Call for Towing Services
Sometimes, the issue might not be something you can fix yourself or at a regular garage. If you’re feeling unsure about the cause of the shaking, or if it’s getting progressively worse, it’s best to call for help. In these cases, a towing company like Rescue & Towing can provide roadside assistance and transport your car to a trusted mechanic if needed.
If you’ve already tried fixing the tires, wheel alignment, or suspension and the shaking persists, don’t risk driving your car at high speeds. Call Rescue & Towing for quick and reliable service. They can help assess the situation and make sure your car is safe to drive again.
5. Conclusion
Driving a car that shakes at high speeds can be unnerving and potentially dangerous, but the good news is that there are several ways to address the issue. From tire balancing and wheel alignment to checking the suspension, many of the solutions are relatively simple and can be done quickly. If you’re unsure about handling it yourself, or if the problem persists despite your best efforts, don’t hesitate to contact a professional. For those in need of fast, reliable towing or roadside assistance, check out Rescue & Towing for top-notch service.
