What Causes Car Vibration?

[EmiliaFitz]

Car vibration can be caused by shaking during startup, idle vibration, high-speed vibration, or aging engine mounts. The specific reasons are as follows: Shaking during startup: Shaking during startup is due to insufficient fuel combustion, resulting in inadequate power output. Idle vibration: Idle vibration may be caused by severe engine carbon buildup, ignition system issues, or unstable oil pressure. High-speed vibration: High-speed vibration can result from excessively high or low tire pressure, abnormal tire wear, rim deformation, shock absorber failure, or tire imbalance issues. Aging engine mounts: Engine mounts act as the vibration absorption system for the engine, absorbing minor vibrations during operation. If the engine mounts are faulty, these vibrations can transfer to the steering wheel and the cabin, causing the car to shake.
