What Causes Body Vibration During High-Speed Driving?
1 Answers
High-speed body vibration causes: 1. Front wheel alignment angle deviation, excessive toe-in; 2. Low front tire pressure or tire imbalance due to repairs; 3. Front wheel rim deformation or incorrect number of tire bolts; 4. Loose installation of transmission components, bent drive shaft, power imbalance, front axle deformation; 5. Shock absorber failure, inconsistent stiffness of front leaf springs. When vibration occurs at higher speeds and causes steering wheel shake, you can first lift the drive axle, secure the front wheels with safety blocks, start the engine and gradually shift into higher gears to reach the final test vibration speed. If both the body and steering wheel vibrate at this point, it indicates transmission system-induced vibration.
