What Causes Friction Noise When a Car Drives at Low Speed?

[LeTalia]

Possible causes of friction noise when a car drives at low speed are as follows: 1. Abnormalities in the car's suspension components. The suspension system includes links, springs, shock absorbers, and stabilizer bars. If any of these components malfunction, it may lead to unusual noises. 2. Issues with the braking system, such as excessively thin brake pads, uneven wear between the brake disc and brake pads, or faults in the brake caliper, master cylinder, or wheel cylinder. 3. Loose engine belt. You can try pinching the drive belt with your fingers and twisting it (ensure the engine is cool during this operation). The twisting angle should generally be less than 90 degrees; otherwise, the belt tension needs adjustment. 4. Aging components, which may occur in areas with rubber parts. Pay special attention to the engine mount rubber pads—check if they have hardened or cracked.
