What Causes Vehicle Shaking?
2 Answers
Causes of car shaking can be divided into the following situations: 1. During startup: Shaking occurs due to insufficient vehicle power caused by incomplete fuel combustion; 2. During idling: Shaking is caused by severe engine carbon deposits, ignition system issues, or unstable oil pressure; 3. At high speeds: Shaking results from either excessively high or low tire pressure, abnormal tire wear, rim deformation, shock absorber failure, or tire dynamic imbalance; 4. Other scenarios: Fuel supply system malfunctions leading to unstable oil pressure can easily cause inconsistent mixture concentration, resulting in shaking; aging engine mounts are also a common cause of shaking.
As someone who frequently drives for trips, I've encountered vehicle shaking several times, especially when the steering wheel shakes violently at high speeds, which scared me into a cold sweat. The main reasons? Unbalanced tires or incorrect tire pressure are the most common causes; uneven tire wear or unrepaired damage after a flat tire can also cause this. Problems with the engine's ignition system, such as burnt spark plugs or faulty coils leading to misfires, can make the car shake noticeably at idle. Aging suspension components like shock absorbers can make the ride unbearable over speed bumps or rough roads. Warped brake rotors or damaged drive shafts can also cause abnormal vibrations. Remember, don't delay addressing shaking, as it can damage tires or suspension—get it checked at a repair shop promptly. Regular maintenance of tires and the engine can prevent this issue, ensuring a safe and comfortable journey.
