Our cars are not just means of transport, but also places of refuge where we can usually enjoy a pleasant background noise. From the gentle hum of the engine to the soothing sounds of the radio – all of this contributes to a relaxing driving experience. But what happens when this is suddenly disturbed by strange noises?
In such moments, we are asked to correctly interpret the acoustic signals of our vehicle and possibly identify deeper problems. Is the noise harmless and easy to fix or an alarming sign of a technical fault? The correct assessment can be crucial to ensure both the performance of the vehicle and your own safety on the road.
Sometimes it’s not just the tires that squeak
A common sign of worn brake pads is a squeaking or grinding noise. In such cases, it is advisable to check the brake pads as soon as possible and replace them if necessary, which usually does not require any special tools. Nevertheless, it is important to ensure that the brakes are correctly adjusted after replacement. If you have brake calipers or complex parts of the braking system, you should call a specialist to avoid taking any safety risks.
A faulty V-belt can cause serious engine problems because it drives various components such as the alternator, water pump and power steering. Typical symptoms are often signaled by a squeaking or creaking of the belt. A belt change can be done yourself, but it is important to check the correct tension of the new belt to ensure it is working properly.
Clattering noises when accelerating and braking
Worn shock absorbers or faulty chassis components can cause noises that sound like an oncoming rattle. It is important to check the suspension regularly. Several components of the exhaust system, such as the catalytic converter, muffler or connecting pipes, can become loose over time. If parts are no longer properly attached, they hit the underbody of the vehicle.
In certain speed ranges, rattling can also come from engine or transmission parts. For example, worn engine mounts (which support the engine in the engine compartment) can cause the engine to vibrate and make noise. It is advisable to have a thorough inspection carried out by a mechanic immediately to identify and repair potential damage early. Regular maintenance helps enormously to extend the life of the vehicle components.
Humming is not just a bear in the woods
If tires are not properly balanced, this can lead to vibrations that are perceived as a humming noise, especially at higher speeds. It is important to regularly check the tires for damage and the correct tire pressure to avoid such problems. A typical sign of worn or damaged wheel bearings is a humming noise that becomes louder when turning or driving on uneven roads. If you suspect this, it should be checked by a specialist as soon as possible and replaced if necessary.
Worn shock absorbers or other suspension components can cause the vehicle to become unstable and make noise when driving. An inspection of the suspension is advisable here. A humming noise can also be caused by problems in the drivetrain, such as a faulty gearbox or differential. Another potential problem could be the engine mounts. If these are worn out, the engine will start to vibrate when driving. Don’t ignore such noises, as they can indicate serious technical problems that will worsen over time!
If you notice a low humming or even high-frequency, constant whirring noise while driving (the reasons may well be similar), you should listen carefully and determine under which conditions the noise is particularly noticeable. However, if you are unable to identify the cause yourself, it is advisable to visit a specialist or workshop to have the vehicle checked thoroughly.
