What Causes Car Shaking at High Speeds?

[StAurora]

The reasons for car shaking at high speeds are: 1. Uneven brake disc surface with excessive radial runout; 2. Significant deviation in wheel alignment data; 3. Tire pressure being too high or too low; 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. Solutions for high-speed car shaking include: 1. Inspect tires, tire pressure, rims, and left/right shock absorbers; 2. Perform dynamic balancing and four-wheel alignment; 3. Check engine mount cushions and transmission mount cushions; 4. Replace regular tires; 5. Add vibration damping sleeves to the drive shaft.
