What causes the buzzing noise when driving between 100 to 120 km/h?

The reason for the buzzing noise when driving between 100 to 120 km/h is: resonance phenomenon occurs. The interior panels of the car are fixed to the body with clips. As the vehicle's mileage increases, these clips may become loose. If the interior panels are loose, resonance and abnormal noises will occur during driving. There are also some rotating components on the car chassis, such as the drive shaft, which may also cause resonance. Car resonance occurs when the vehicle reaches a certain speed where the vibration frequency matches the resonance frequency, causing severe shaking of the car body. This refers to a physical system vibrating with greater amplitude at specific frequencies compared to others, and these specific frequencies are called resonance frequencies.

When I drive on the highway at 100-120 km/h, I sometimes hear a humming noise, which is likely due to a problem with the wheel hub bearing. Over time, bearings wear out, causing the humming sound to appear at specific speeds. Additionally, improper tire balancing can also cause this issue, as uneven tire wear can make the wheels wobble. Another possibility is loose brake pads or wheel hub bolts causing vibrations. I've encountered similar situations on the road before. I recommend you first check the tire pressure and wear condition. If everything seems normal, take your car to a repair shop as soon as possible for a wheel hub bearing inspection. Ignoring this issue not only affects driving comfort but may also lead to unstable wheels and potential danger. Remember to regularly inspect these components during maintenance to prevent problems from accumulating.

A humming noise occurs within the speed range of 100-120 km/h, a topic I frequently encounter among fellow car enthusiasts discussing, primarily related to wheel hub or drivetrain malfunctions. Aging wheel hub bearings can produce a low-pitched humming sound, especially noticeable at high speeds. Additionally, poor tire balance is a common cause, as it shifts the wheel's center of gravity, leading to resonance. Another possibility is wear on the half-shaft or driveshaft, causing the sound to reverberate under the car. During long drives, I pay close attention to these issues; upon hearing any unusual noise, I immediately reduce speed to a safe level. A simple test is recommended: after stopping, gently shake the wheel to check for looseness, then seek a professional shop for a comprehensive diagnosis. Regular maintenance of the wheel hub system can effectively prevent humming noises.

When the speed reaches 100-120 km/h, there's a noticeable humming noise, which I often observe while driving. This is mostly due to wheel hub bearing issues. A faulty bearing produces a continuous humming sound and may transmit vibrations to the steering wheel. Another possible factor is unbalanced tire dynamics, such as uneven tire wear or improper installation, leading to unstable wheel rotation. Ignoring this can be distracting at high speeds and even pose a risk of losing control. If you hear such noise, it's best to minimize high-speed driving and have a technician inspect it promptly.
