How to Solve the Friction Noise When the Car is Driving at Low Speed?
2 Answers
Solutions for friction noise when the car is driving at low speed are as follows: 1. Identify the location of the noise: You can lift the car with a jack, have one person drive the car in gear inside the vehicle, and another person determine the location of the noise under the car. 2. If the noise occurs near the tires and the wheels and bearings have been ruled out: Then it may be the noise caused by the friction between the brake pads and the brake disc. Generally, brake pad noise is mostly caused by hard spots on the brake pads rubbing against the brake disc, and small noises can be ignored; if the noise is loud, you can remove the brake pads, sand them down with sandpaper, and then reinstall them, which can usually solve the problem. 3. If the noise is at the connection between the transmission and the engine: Then it may be the noise caused by damage to the clutch plate or release bearing. If the noise is inside the transmission, it may be caused by abnormal wear of the first or second gear.
I recently encountered a similar situation where my car made a squeaky friction noise at low speeds, which was quite annoying. After inspection, I found that the brake pads had some issues, with small stones or dust stuck on them, causing the noise to be particularly noticeable when the brake discs rubbed. At low speeds, it's easier to hear because the wheels rotate slowly, and the noise isn't masked by other sounds. I tried removing the wheels myself to clean the brake pads, wiping off the dirt with a cloth, and the noise reduced significantly. If this doesn't work, the problem might be more complex, like aging rubber bushings in the suspension system or uneven tire wear causing friction noises. It's advisable to pay more attention to wheel hygiene in daily use, cleaning debris from the tire surface after parking to avoid worsening the issue. If the noise persists, don't delay—take it directly to a repair shop. They can quickly identify the root cause by lifting the chassis, saving both money and hassle.
