What Causes Abnormal Noises While Driving?
2 Answers
Abnormal noises while driving can be categorized into brake noises, engine guard plate noises, center console noises, shock absorber noises, etc. The specific causes require detailed analysis. Brake noises: If the friction material of the brake pads is too hard, you can use coarse sandpaper to sand the brake pads; if sand or dust particles enter the brake disc, causing a hissing sound from the brake, pressing the brake hard can solve the issue. If there is intermittent, sharp noise when braking, it indicates severe wear on the brake pads or brake disc, which should be replaced promptly. Engine guard plate noises: After frequent driving, screws may shift. Check if the engine guard screws are loose or if the engine guard plate and negative plate are loose. Center console noises: The resonance phenomenon when the car is idling is caused by the idle resonance between plastic parts. This situation usually appears or disappears with seasonal changes and the thermal expansion and contraction of gaps between plastic parts, and it generally does not affect daily safe driving. Shock absorber noises: Due to the structure of the vehicle's shock absorber, when the vehicle passes over rough road sections, the entire shock absorber is compressed, thereby compressing the external spring. After the vehicle passes the uneven road section, the spring's elasticity will reset the shock absorber, and this compression and reset process of the shock absorber will be accompanied by a "hissing" or "sizzling" exhaust and deflation sound.
I've been driving for decades and have dealt with various abnormal noise issues. The most common is the clicking sound from small stones stuck in tire treads, especially noticeable at high speeds. Aging suspension components like shock absorbers can produce squeaking and creaking sounds when going over potholes, more frequently triggered on poor urban roads. Worn brake pads cause high-pitched squealing during braking, which is not only irritating but potentially hazardous. A loose engine belt makes a whirring noise, and if cracked, becomes even more dangerous. Loose interior parts like windows increase wind noise significantly. Once during a long trip, I heard a rattling sound that turned out to be a failing wheel bearing - timely repair prevented an accident. I recommend regular maintenance checks, especially for city commuters where wear occurs faster. Small issues left unattended can become major hazards. Always inspect tires for stones before driving, and visit a professional shop immediately if any abnormality is detected.
