Any extraneous sound in the car causes the driver to worry and think about upcoming expenses. However acoustic diagnostics can help determine the source of the problem even before a service visit. The ability to distinguish the nature of the noise allows you to understand whether it is possible to continue driving or whether you should stop immediately.
Most often, drivers encounter the following types of sounds that indicate wear of parts:
-
A high-pitched whistle from under the hood usually indicates belt slippage generator or other attachments. This sound intensifies when you press the gas or turn on powerful electrical appliances. The problem is solved by tightening the belt or replacing it if the rubber has lost its elasticity.
-
A dull knock when driving over bumps indicates a malfunction in the suspension elements. These could be worn stabilizer links, ball joints or silent blocks. Ignoring this sound leads to poor handling and accelerated tire wear.
-
A uniform hum that increases with increasing speed is most often produced by a faulty wheel bearing. This sound is similar to the rumble of an airplane and changes in tone when you turn the steering wheel. Operating a car with a damaged bearing is extremely dangerous, as the wheel can jam while driving.
-
A metallic grinding sound when braking indicates complete wear. brake pads. The friction layer has worn off and the metal base of the pad is scratching the brake disc. This requires immediate intervention, as braking efficiency is critically reduced.
-
A hissing noise under the hood often indicates a problem cooling system tightness or vacuum pipes. If the sound is accompanied by steam, it means that antifreeze is getting into the hot engine, which threatens to overheat the engine.
Paying close attention to the sound of your trip helps prevent serious accidents. Most faults at an early stage are eliminated faster and cheaper than major repairs of components and assemblies. Regular technical inspection allows you to identify hidden defects even before the appearance of extraneous noise.
