Here Are the Most Common Reasons Why is My Car Squeaking

A vague, undefined squeak is coming from your car. You’re not sure of it’s exact origin, but you can hear it and are at least able to identify the direction from which it’s coming (in relation to you in the driving seat). This isn’t a good situation in which to find yourself, and the less you know about the inner workings of your car, the worse it will feel.


If you have no idea where to start looking, but would like to narrow down the possibilities before taking it to a shop for repairs or would like to identify the problem so that you can repair it yourself, then you’re in luck, because I can help you.

I will always suggest that you try to identify the problem yourself, before taking it into a garage because, even without having any mechanical knowledge yourself, the more you can tell your mechanic about the sound, the less of their time, and your money will be spent trying to find the problem.

Identifying When and From Where You Hear the Squeak

During Acceleration

This would indicate that your fan belt is worn out, and needs replacing.

If you would like to replace the belt yourself, I recommend you use this video, or one specific to your car, as a guide:

During Turning

This likely means that the problem is steering related, either too little fluid in the power steering system or a faulty power steering pump.

Another possible, but less likely fault, is worn wheel bearings. To check, turn the steering wheel to the right while driving. If you hear a squeak from the left, then your left wheel bearing may be worn. If you turn left, and the squeak comes from the right, then the fault is with your right wheel bearing.

Here’s a video showing how easy it can be to change your power steering fluid:​

If the issue is with the pump, it’s recommended that you take your vehicle into a shop, to have it changed professionally, as this tends to be a very involved process, requiring a knowledge and experience to do safely, and correctly.

During Deceleration

​Probably the most common cause of squeaking cars, your brake pads may need to be replaced. If the weather is cold and wet, then take a drive to check if the squeaking persists, as it may disappear once the brakes are warm and dry.

​If you think you need to change your brake pads, it’s not the end of the world, as pads are pretty cheap, and the process to inspect, and replace them is relatively straightforward:

During Normal Operation / All of the Time

Worn Alternator bearings will cause a squeaking noise during their operation. Because alternators are in constant operation, the noise created by any worn parts would be fairly constant as well.This is another job best left to professionals.

A new Alternator will cost you around $100.00, with labor for the job likely coming up to a similar amount.​

If you take the new part into your local garage along with your car, they should be happy to install it for you. Doing it this way may not save you any money, but it ensures that you aren’t overcharged for parts.​


As you can see, an undefined squeak from somewhere in your car could be indicating a variety of problems, and unless you know what to look for, it can be stressful to deal with.

Even if you know nothing about cars, and are planning to take yours to a garage to have it diagnosed, and repaired, this article should at least have allowed you to relax slightly, by letting you know what possible faults your car has, none of which are major issues, and all of which are relatively easy, and cheaply repairable.​
