What is the problem of high-speed body shaking?
2 Answers
High-speed body shaking issues are as follows: 1. Uneven brake disc surface: The brake disc surface is uneven with a large radial runout, caused by uneven braking force or brake pad misalignment. 2. Excessive tire pressure: When the vehicle's tire pressure is too high, the shaking is particularly noticeable when driving at high speeds on uneven roads, making it easy for the driver to feel the body shaking and veering. 3. Severe tire wear: Severe tire wear with significant imbalance in dynamic balance. Due to uneven wear or large dynamic imbalance, the tire may jump during high-speed operation, causing the body to shake. 4. Engine issues: Generally caused by fuel quality or ignition problems. At high speeds and under high load, fuel quality and ignition determine the power output. If either is abnormal, it can lead to engine weakness and shaking.
When driving on the highway and suddenly feeling the car body shaking or unstable, the most common reason is tire issues. I've encountered this situation several times during long trips, and carefully checking tire balance and pressure can solve most problems. Tires can easily deform or wear unevenly after prolonged use, causing severe vibrations at high speeds. It's essential to ensure proper tire pressure and balanced wheels regularly; otherwise, it may strain the suspension system over time. Once, I forgot to check the tire pressure, and the car shook like a roller coaster. It's recommended to perform tire alignment and balancing every 5,000 kilometers—don't wait until the problem severely affects driving safety.
