What are the causes of high-speed body shaking?
1 Answers
High-speed body shaking causes: 1. Front wheel alignment angle deviation, excessive toe-in; 2. Low front tire pressure or tire imbalance caused by repairs; 3. Front wheel rim deformation or unequal number of tire bolts; 4. Loose installation of transmission system components; 5. Drive shaft bending, dynamic imbalance, front axle deformation; 6. Shock absorber failure, inconsistent front leaf spring stiffness, frame deformation; 7. Engine issues, usually caused by fuel quality or ignition problems. Under high-speed and high-load conditions, fuel quality and ignition determine power output. If either is abnormal, it can cause engine weakness and shaking.
