What Causes Vehicle Body Vibration at High Speeds?
1 Answers
Vehicle body vibration at high speeds can be caused by: 1. Uneven brake disc surfaces with significant radial runout; 2. Rim deformation; 3. Improper tire pressure (too high or too low); 4. Large deviations in wheel alignment data; 5. Abnormal tire wear; 6. Tire dynamic imbalance; 7. Shock absorber failure; 8. Engine power issues. Solutions for vehicle body vibration at high speeds include: 1. Inspecting and adjusting front wheel alignment angles and toe-in; 2. Performing wheel dynamic balance checks; 3. Adjusting tire pressure or replacing tires; 4. Conducting driveshaft dynamic balance inspections; 5. Using high-quality engine oil; 6. Checking the engine ignition system.
