What are the causes of high-speed body vibration?
2 Answers
Here are the reasons for high-speed body vibration: 1. Uneven brake disc surface with significant radial runout; 2. Large deviation in wheel alignment data; 3. Excessive or insufficient tire pressure; 4. Abnormal tire wear; 5. Rim deformation; 6. Shock absorber failure; 7. Tire dynamic balance issues; 8. Automatic transmission lock-up clutch problems; 9. Engine power issues. Methods to address high-speed body vibration: 1. Inspect tires, tire pressure, rims, and left/right shock absorbers; 2. Perform dynamic balancing and four-wheel alignment; 3. Check engine mount pads and transmission mount pads; 4. Replace regular tires; 5. Add vibration dampening sleeves to the drive shaft.
Recently, while driving on the highway, my car body was shaking violently, which made me a bit nervous. This kind of shaking usually stems from tire issues, such as uneven tire pressure or unbalanced tires. When you're driving at high speeds, the wheels rotate too quickly, and if there's a slight imbalance, it can cause the car body to vibrate, making it feel like the car is bouncing around. In severe cases, the steering wheel may also shake, affecting control. Additionally, uneven tire wear or excessively high or low tire pressure can exacerbate this situation. Sometimes, a simple tire pressure adjustment can solve the problem. It's recommended to check the tire pressure before driving. If the shaking is severe, it's best to go to a professional shop for a dynamic balance test to avoid danger. Personally, I maintain my tires regularly, which helps reduce the occurrence of shaking.
