Tire imbalance and wheel alignment issues can cause noticeable vibrations at lower speeds such as 60 mph, while not being as pronounced at higher speeds like 70 mph. When a tire is imbalanced, it means that there is uneven distribution of weight around the tire and wheel assembly. This can lead to shaking or vibration as the tire rotates. Similarly, if the wheels are not properly aligned, they may not be pointing straight ahead, causing the tires to wear unevenly and create vibrations. It’s important to regularly check and maintain proper tire pressure to minimize these issues. Additionally, road conditions can also contribute to the intensity of vibrations felt in a car. Uneven or bumpy roads can exacerbate any existing tire imbalance or wheel alignment problems. With that said, worn out or damaged suspension components can also contribute to car shaking at different speeds without proper maintenance and care.
3. Worn Out or Damaged Suspension Components
Road conditions, such as uneven or bumpy surfaces, can exacerbate any existing issues with worn out or damaged suspension components, leading to vibrations and a less smooth driving experience. The physics of car shaking at specific speeds like 60 mph but not 70 mph can be attributed to the resonance frequency of the worn-out or damaged suspension components. When the wheels hit a certain frequency of vibration due to road conditions, it causes the car to shake. To diagnose and resolve this issue, it is recommended to consult a professional who can thoroughly inspect the suspension system and identify any worn-out or damaged components. They may suggest solutions such as replacing worn-out bushings, shocks absorbers, or other parts that are causing the vibrations.
