What Causes a Zizzing Sound from the Front Left Wheel of a Car?
2 Answers
The reasons for a zizzing sound from the front left wheel of a car are as follows: 1. There are foreign objects on the tire, such as stones or cans stuck to it. Timely inspection and cleaning will suffice. 2. Brake pad noise, which is likely due to the brake pads being nearly worn out and needing replacement. Solutions are as follows: 1. Check the thickness: A new brake pad is generally about 1.5cm thick, and the thickness gradually decreases with use due to friction. 2. Feel the pressure: If you notice a significantly lower pedal position during emergency braking, it could mean the brake pads have lost most of their friction and must be replaced immediately to avoid serious accidents. 3. Listen for sounds: If a metallic scraping or squealing noise accompanies light braking (which could also be due to initial break-in of newly installed brake pads), the brake pads must be replaced immediately. 4. Check the warning light: Use the brake warning light on the dashboard as an indicator for whether the brake pads need replacement.
Recently, my car had a similar issue, and the buzzing sound was quite annoying. It’s usually caused by worn or rusty brake pads rubbing against the brake disc, creating noise. When the brake pads thin out, they tend to squeak. Another common cause is a damaged wheel bearing—if the bearing is faulty, the noise becomes more noticeable during turns or acceleration. It could also be a problem with the steering system, like loose or worn tie rods. Sometimes, small stones or debris stuck in the wheel hub can also cause such sounds. For safety, I suggest doing a quick check: after parking, manually spin the wheel to see if the noise persists. If you notice anything unusual, it’s best to visit a professional repair shop for a thorough inspection as soon as possible. Ignoring it could lead to bigger, costlier, and more dangerous problems. Paying attention to these details during daily driving can prevent major issues, especially since it’s the left front wheel—extra caution is needed during turns.
