Car shakes at 70+ mph may be due to alignment issues or unbalanced tires. Get a professional inspection for accurate diagnosis and repair.
Experiencing a shaking sensation in your car when driving at high speeds can be both alarming and dangerous. The root causes can range from something as simple as unbalanced tires to more serious issues like suspension problems or misaligned wheels.
It is crucial to address this issue promptly, as driving with a shaking car can not only be uncomfortable but also affect your vehicle’s overall performance and safety. We will explore the common reasons why your car shakes when driving over 70 mph and provide you with potential fixes to ensure a smooth and safe driving experience.
Possible Causes
Experiencing car shakes when driving above 70 mph? There are various causes for this unsettling issue, such as tire imbalance, worn-out suspension components, or misalignment. To resolve the problem, get your tires balanced, inspect and replace any damaged suspension parts, and align your car’s wheels properly.
Unbalanced Tires
One of the potential causes for your car shaking when driving at high speeds, particularly over 70 mph, is unbalanced tires. When the tires are not balanced correctly, they can create vibrations that propagate throughout the vehicle, leading to an uncomfortable driving experience.
Unbalanced tires can be caused by regular wear and tear or improper installation. Over time, the distribution of weight on the tires can become uneven, resulting in an imbalance. Additionally, if the tires were not mounted and balanced correctly during installation, this can also lead to an imbalance.
Wheel Alignment Issues
Poor wheel alignment can also be a potential cause for your car shaking at higher speeds. When the wheels are not properly aligned, it can affect the way the tires make contact with the road surface. This misalignment can lead to an uneven distribution of forces, causing vibrations throughout the vehicle.
Various factors can lead to wheel alignment issues. Potholes, hitting curbs, or even normal wear and tear over time can gradually affect the alignment of the wheels. Furthermore, if the vehicle undergoes any modifications or aftermarket installations, such as lowering or lifting kits, it can result in misaligned wheels if not done correctly.
Worn Suspension Components
Another possible cause of your car shaking when driving over 70 mph could be worn suspension components. The suspension system plays a crucial role in maintaining stability and smoothness while driving. With regular use, the various components of the suspension system can wear out.
When suspension components such as bushings, struts, shocks, or control arms are worn, they can cause excessive movement and instability, resulting in vibrations and shaking at higher speeds. These worn components may need to be replaced or repaired by a qualified mechanic to restore the smoothness of your vehicle’s ride.

Diagnostic Steps
When your car shakes when driving over 70 mph, it’s essential to conduct diagnostic steps to identify the root cause. By following these diagnostic steps, you can pinpoint the issue and determine the necessary fixes to ensure a smoother driving experience.
Check Tire Balance
To diagnose the shaking, begin by checking the tire balance. Imbalanced tires can cause vibrations, especially at higher speeds. Have a professional inspect the tires for proper balance and make adjustments as needed.
Inspect Wheel Alignment
Next, it’s crucial to inspect the wheel alignment. Misaligned wheels can lead to vibrations and shaking at higher speeds. Ensure that the wheels are properly aligned, and if necessary, have a professional realign them to prevent further issues.
Inspect Suspension Components
Lastly, thoroughly inspect the suspension components of your vehicle. Worn-out or damaged suspension parts can contribute to the shaking sensation. Check the shock absorbers, struts, and other components for any signs of wear or damage, and replace them if necessary to restore smooth driving.
Fixes
Fixes for a car that shakes when driving over 70 mph are crucial to ensure safety and performance. Addressing issues like tire balancing, wheel alignment, and suspension repairs can help resolve the problem effectively.
Tire Balancing
Tire balancing ensures even weight distribution, minimizing vibrations at high speeds.
Wheel Alignment
Wheel alignment corrects the angles of the wheels, preventing uneven wear and shaking.
Suspension Repairs
Suspension repairs involve fixing worn-out components to improve stability and smoothness.

Importance Of Timely Fixing
Car shakes over 70 mph can indicate serious issues. Addressing promptly is crucial for various reasons.
enhanced Safety
Immediate fixing reduces potential accidents due to instability at high speeds.
prevention Of Further Damage
Early repairs prevent extensive damage to other components caused by prolonged shaking.
improved Ride Comfort
Timely fixes ensure a smoother and more enjoyable driving experience for the vehicle occupants.
When To Consult A Professional
When experiencing persistent shaking in your car, especially when driving over 70 mph, it's crucial to assess the situation and determine whether it requires professional attention. Ignoring the issue could lead to further damage and compromise your safety on the road.
Persistent Shaking
If your car consistently shakes at high speeds, it's essential to consult a professional mechanic. Persistent shaking could indicate severe mechanical or suspension problems, which, if left unaddressed, may lead to dangerous driving conditions and potential accidents. Seeking professional help can diagnose and fix the underlying issue, ensuring a smoother and safer driving experience.
Lack Of Mechanical Knowledge
- In cases where you lack in-depth mechanical knowledge, seeking professional assistance is advisable. Without the necessary expertise, attempting to diagnose and repair the issue on your own could lead to further complications and potential safety hazards.
- Consulting a professional ensures that the shaking problem is accurately identified and effectively resolved, preventing any further damage to your vehicle. Lack of mechanical knowledge underscores the importance of entrusting the issue to a skilled professional.
Complex Suspension Issues
- Complex suspension problems linked to high-speed shaking require specialized care and expertise. Consulting a professional ensures that your vehicle’s suspension is thoroughly inspected and any underlying complexities are addressed with precision.
- Professional intervention becomes crucial when dealing with complex suspension issues, as amateur attempts may exacerbate the problem and compromise the overall performance and safety of your vehicle.
