What are the causes of car body shaking when driving at high speed?
2 Answers
Vehicle running at high speed body shaking causes are: 1. The vehicle's ignition system has malfunctioned; 2. Loose components in the ignition system; 3. Severe engine carbon buildup; 4. Aging engine components; 5. Excessive throttle carbon deposits; 6. Air filter not replaced in time; 7. Excessive carbon deposits in the fuel injectors; 8. Problems with the ignition system; 9. Unstable oil pressure. Body shaking is a common condition encountered by many car owners. If the owner notices significant body shaking when starting the vehicle or when the vehicle is idling with the engine running, it may indicate a problem with the vehicle and should be inspected promptly.
I've also experienced body vibration when driving on the highway, and it's really uncomfortable. The most common cause is tire issues, such as uneven tire wear or slight deformation, where the imbalance force gets amplified at high speeds, causing shaking. Wheel imbalance is another major factor – if the balancing weights fall off, the tire rotation becomes unstable. Additionally, worn suspension components like shock absorbers or ball joints can intensify body sway. Problems with the driveshaft, such as loose universal joints, can also cause vibration due to abnormal power transmission at high speeds. I've also heard of brake disc deformation causing vibrations. It's advisable to first visit a professional shop to check the tires and balance. Don't overlook safety, as this vibration isn't just annoying but could also lead to steering loss, especially on curves. For highway driving, regular maintenance is crucial – I now check my tires every 10,000 kilometers.
