What Causes Steering Wheel Vibration When Driving at 100 km/h?

[OMichael]

The reasons for steering wheel vibration when driving at 100 km/h are: 1. Balance weights falling off or being damaged; 2. Significant differences in tire pressure among the four tires; 3. Large deviations in four-wheel alignment angles; 4. Shock absorber failure; 5. Frame deformation; 6. Excessive backlash in the driven gear. Solutions to steering wheel vibration when driving at 100 km/h include: 1. Checking and adjusting tire pressure; 2. Inspecting wheel balance and correcting tire centripetal force; 3. Checking four-wheel alignment; 4. Inspecting and repairing the chassis, braking system, and engine mounts. Precautions for high-speed driving are: 1. Fastening seat belts; 2. Avoiding phone calls while driving; 3. Prohibiting throwing items out of the vehicle.
