What Causes Vehicle Shaking?
1 Answers
Vehicle shaking causes: 1. Shaking during startup: Mainly due to incomplete fuel combustion resulting in insufficient power, especially when fuel and lubricant temperatures are low, requiring more throttle input to meet power demands; 2. Idle shaking: Causes include severe engine carbon buildup, ignition system issues, unstable oil pressure, and aging engine components; 3. High-speed shaking: Overinflated or underinflated tires, abnormal tire wear, rim deformation, shock absorber failure, tire imbalance, and significant wheel alignment deviations can all cause vehicle shaking. Vehicle shaking may also relate to worn engine mounts - the engine's vibration damping system that absorbs minor vibrations during operation. If engine mounts fail, these vibrations transmit to the steering wheel and cabin, causing shaking at idle.
