What are the causes of high-speed body vibration?
1 Answers
High-speed body vibration is caused by: 1. Uneven brake disc surface; 2. Large deviation in wheel alignment data, especially incorrect front wheel alignment angles and excessive toe-in; 3. Tire pressure being too high or too low - higher speeds with overinflated tires cause more severe body vibration, while underinflated tires result in floating sensation and pulling; 4. Abnormal tire wear; 5. Rim deformation - when tires are mounted on deformed rims, the tires also deform, leading to uneven surfaces and incorrect wheel dynamic balance, causing vibration during driving; 6. Damaged shock absorbers - at high speeds, the impact from the road surface to the tires is transmitted to the body without attenuation, causing vibration throughout the entire vehicle.
