What Causes Vehicle Vibration During Driving?

The reasons for vehicle vibration during driving include: damaged spark plugs, poor fuel quality, excessive carbon buildup, unstable oil pressure, etc. It is necessary not only to inspect the throttle valve and idle speed motor but also to check if there is excessive carbon buildup or dirt in the intake tract. If there is too much buildup, it can alter the cross-sectional area of the air passage, preventing the control unit from precisely regulating the idle intake air volume. This can result in an overly rich or lean air-fuel mixture, leading to abnormal combustion and engine vibration. If you have already cleaned the engine carbon deposits, changed the oil and spark plugs, but still experience body vibration while driving, check whether the fuel supply pressure and intake pressure sensors are functioning normally. Abnormal fuel pump supply pressure or incorrect values and poor performance of the intake pressure sensor can also cause body vibration. In such cases, it is necessary to check the oil pressure and replace components if needed.

I've been driving for most of my life and have seen plenty of vehicle shaking issues. The most common cause is tire problems, such as uneven tire pressure or severe wear, which makes the steering wheel shake violently at high speeds—requiring dynamic balancing adjustments. Next is aging suspension systems, like worn-out shock absorbers or loose control arms, causing uncomfortable shaking over speed bumps. I remember one long trip where the car body shook violently, and inspection revealed front axle wear. Never underestimate shaking—it may hide major hazards. I recommend regularly checking tire tread and pressure, developing the habit of timely repairs, and ensuring safe driving to enjoy the pleasure of driving for years to come.

I bought my car just two years ago and have already experienced shaking troubles: initially slight shaking at low speeds, later the entire steering wheel wobbling at high speeds. After searching online, I thought the tires were damaged, but the mechanic said it was due to warped brake discs. My advice to friends is not to delay—first check if the tire pressure is standard and clean out any stones stuck in the treads. If the problem persists, inspect the brakes or suspension. Spending a little money to fix it early can save you from driving in fear and also prevent increased fuel consumption and reduced peace of mind.

When I notice vehicle shaking, my immediate concern is safety risks: it could be due to broken engine mounts or an imbalanced driveshaft, which may lead to loss of control at high speeds with severe consequences. I recommend slowing down immediately and pulling over to check for any visible tire abnormalities. If unsure, don't take risks—have it towed directly to a repair shop. Never overlook potential dangers to save time. Addressing such issues promptly is the correct approach.
