What are the common causes of car body vibration?
2 Answers
If slight vibration or deviation is noticed in the car body during driving, it is generally caused by tire-related issues. The following introduces the functions of tires: 1. Supporting the entire weight of the vehicle: bearing the load of the car and transmitting forces and moments in other directions. 2. Transmitting traction and braking torque: ensuring good adhesion between the wheels and the road surface to improve the car's power performance, braking performance, and passability. Working together with the car suspension to mitigate impacts during driving and dampen resulting vibrations. 3. Preventing severe vibrations and premature damage to car components: adapting to the vehicle's high-speed performance and reducing driving noise, ensuring driving safety, handling stability, comfort, and energy efficiency.
I've often encountered body shaking issues during my years of driving, with the most common cause being tire problems. For example, unbalanced tires or improper air pressure can cause severe shaking at high speeds. Too low tire pressure leads to tire deformation, while too high makes the car unstable. Suspension system failures are also common, such as aging shock absorbers causing uneven bumps. Other causes include warped brake rotors, damaged wheel hubs, or unbalanced drive shafts. Once, my car shook like it was dancing, and after inspection, it turned out to be uneven tire wear—replacing the tires fixed it. For daily driving, it's recommended to regularly check tire pressure and perform wheel alignment to ensure safety first, and not to overlook small issues that could lead to bigger problems. Regular maintenance is key to peace of mind and saving money.
