Why Does the Vehicle Make Abnormal Noises?
3 Answers
Here is an introduction to the "zi zi" abnormal noise during vehicle driving: When a vehicle makes a "zi zi" noise, it is possible that there is a problem with the brake pads. The brake pads may have worn thin, causing direct contact between the brake drum and the vehicle, resulting in metal friction. In this case, the brake pads need to be replaced. Additional information on when to replace brake pads: 1. Front brake pads generally need to be replaced every 30,000 to 50,000 kilometers. 2. Rear brake pads can be replaced after driving approximately 60,000 to 100,000 kilometers. 3. New brake pads are typically about 1.5 centimeters thick, and there is a protrusion at both ends of the brake pads, approximately 3 millimeters. If the thickness of the brake pads is level with this mark, they should be replaced immediately. 4. If a metal friction sound is heard during braking, it may indicate that the brake pads have worn down to the protrusion position, causing friction with the brake disc and producing abnormal noise. Immediate replacement is necessary. 5. If the brake pedal feels lighter than usual or if braking feels difficult or ineffective, it also indicates severe wear and insufficient thickness of the brake pads, requiring prompt replacement.
I often encounter strange noises in my car, as it's common for some sounds to appear after prolonged use. The most frequent issue is aging suspension components, such as worn shock absorbers that creak over bumps, or loose ball joints that produce a clicking sound when turning. The braking system is also prone to noise—worn brake pads can squeal, especially in rainy weather. Unbalanced or cracked tires may cause a humming noise at high speeds. In the engine bay, a loose belt or chain with excessive play can create a hissing friction sound. Loose interior trim, like unsecured door panels, tends to rattle continuously on bumpy roads. Never ignore these noises—they often signal minor issues that, if left unaddressed, can escalate into major problems. I always remind myself to visit the repair shop early for a check-up, saving both money and ensuring driving safety.
There are numerous reasons for vehicle noises, and I've pondered over them many times. When suspension components like shock absorber bushings crack, you'll hear a thumping sound as the car moves, and uneven tire wear can cause a humming noise. The braking system is the most obvious; impurities between the discs and pads result in a squeaky sound. Over in the engine, a faulty belt tensioner can produce a sharp screech, while worn driveshaft splines make unusual noises during acceleration. Some sounds are caused by loose interior parts, like a rattling seat frame that's come apart. From my experience, don't rush to replace parts—start with simpler checks, such as lubricating suspension joints. Regular maintenance is key; I inspect the suspension and brakes every six months. Even if the noise seems minor, don't delay, or repairs will become more time-consuming and costly later.
