What are the causes of body vibration while driving?
2 Answers
The causes of body vibration while driving are: 1. Dirty throttle body; 2. Excessive carbon buildup in fuel injectors; 3. Poor working condition of spark plugs, high-voltage wires, and ignition coils; 4. Malfunctioning fuel supply pressure and intake pressure sensors; 5. Aging engine mounts; 6. Poor tire balance condition; 7. Deformed tire rims. The throttle body is a controllable valve that regulates air intake into the engine. After entering the intake pipe, the air mixes with gasoline to form a combustible mixture, which then burns to generate power. The throttle body connects to the air filter at the top and the engine block at the bottom, earning it the nickname 'the throat of the automobile engine'.
I remember once experiencing severe body vibration while driving on the highway, especially noticeable when exceeding 60 km/h. This is usually related to tire issues. Uneven tire pressure, unbalanced wear, or prolonged lack of wheel balancing can cause unstable wheel rotation, leading to body vibration. Additionally, if the tire tread wears irregularly or becomes out-of-round, the car may feel like it's bouncing while driving. It's recommended to first check if the air pressure in all four tires is consistent, with the ideal values referenced on the label by the door. If that checks out, then proceed with a professional wheel balancing service. Regular maintenance should also include monitoring tire conditions; consider replacing them when wear exceeds half, as continued use not only causes vibration but also compromises safety, increasing the risk of losing control at high speeds.
