Common Car Noises

Common Car Noises Everyone has been in this situation at some point in their driving life and everyone can relate to this problem, we are sure because cars tend to sound strange sometimes. Here we are not talking about the classical and normal “rawring” of the motor, but more like the strange and unusual noises we often prefer to ignore and play the radio louder. Well, let’s face it, facing car problems is definitely not something enjoyable and car repairs definitely don’t sound like an exciting way to spend the day, right?

However, neglecting and ignoring the car noises that are untypical can often lead to major issues and it is about time to brace yourself and face the problem. Mobeo shares with you this guide of the most common car noises and what they might mean. This is particularly helpful for those of you that have just bought a used car and don’t know its history.

Clunking
This noise appears the most often when braking and it usually means that the brake calliper is damaged, missing, or not mounted properly. However, if the clunking noise appears when you go over a bump, this is most certainly a case of a suspension problem.

Flapping
The flapping noise is most commonly a sign that something is interfering with the fan belt.

Grinding
The grinding noise may appear when changing gear and it usually means that you either face issues with your clutch that may be worn out, or in need of adjusting, or that the gearbox is damaged and need repair or replacement.

Hissing/sizzling
These sounds may appear when the engine is first turned off and can be a sign of a coolant or vacuum line leak onto the hot engine, or that the engine is overheating.

Humming/whirring
These noises may change when you accelerate and they usually mean a need of lubricating, or worn universal joints, or problem with the transmission.

Knocking
Knocking noise may mean you are using low-grade fuel that is not good for the engine and you maybe should upgrade it. If you are still wondering which fuel to choose in your situation the smartest thing is to use the fuel recommended in your manufacturer’s handbook.

Loud bang
The loud band noise comes from the backfire, when the air-fuel mixture is not right, or when there is an issue with the catalytic converter.

Noise when turning
If you hear an unusual noise when turning it’s time to have a look at the steering linkage because it is most probably in need of lubricating or replacing.

Popping
This noise can be a sign of numerous issues, including an ignition problem, worn spark plugs and spark plug wires, clogged fuel filter, a problem with the catalytic converter.

Rattling
This can be a loose exhaust system or brake pads.

Roaring
In this case, the issue is most likely to consist of a damaged exhaust.

Scarping
It is often a sign that it is time to replace the brake pads.

Screeching
You may notice this noise when you start up the engine and it often means that the fan belt is probably slipping, or that maybe the water pump has come loose.

Tapping
This noise coming from the engine usually means that you are low on engine oil, or there is a problem with the engine oil system.

Whining
This noise is often a sign for a wear in the transmission or the differential.
