Why My Car Squeaks When Driving?

If you are driving at high speeds and suddenly your car squeaks when driving that’s the most fearful thing to experience. In this post, we will know how to fix the squeaking.

Squeaking noise while driving can be caused by a variety of factors, including a worn-out cambelt or a faulty alternator. In our car squeaks guide, we help you diagnose various problems and explain why it’s critical to maintain your vehicle.

Why My Car Squeaks When Driving?

Take note of when and where the sound occurs. Does it happen, for example, when you start the engine, while the car is idling, accelerating, or turning?

Reasons For Squeaks

The following are some of the possible causes of squeaking in your car while driving:

  • Brake pads that have failed
  • A sloppy belt
  • Steering-related problems
  • Tire issues
  • Lubrication is required.
  • Steering System

1. Worn Out Brakes

These squeaks will occur whenever you apply pressure to your brakes, indicating that they are worn. The squeaky sound is caused by metal coming into contact with metal. You’ll need to replace your brake pads in this case. You may also need to replace the rotors. When the rotors are damaged, the squeaking is caused by the brake pads making improper contact with the rotors.

2. Loose Belts

When accelerating, loose belts squeal. A loose serpentine belt is a common cause of a squeaky car. When you accelerate, the squeaking is most likely caused by the belt. This indicates that the belt has been worn. Driving for an extended period with worn belt risks severe damage.

One, in particular, that does a lot of work is the serpentine belt. It replaces the numerous v-belts that are usually present in your car for all of the different systems, such as the power steering pump, cooling fan, air conditioning compressor, and others.

All of these systems rely more heavily on that single belt during acceleration, which can cause the belt to squeal if it’s old and worn.

3. Problem with the alternator

The noise is undeniably irritating and with reason. If you don’t get the loose or slipping alternator pulley fixed, it could lead to bigger problems in the future. Furthermore, the alternator has bearings that allow the rotor to spin and keep the electricity flowing. When these bearings become old, dirty, or worn out, they make a loud squeaky grinding noise.

4. Tire Problems

In some cases, the sound may be caused by the tire. However, there may be squealing rather than squeaking sounds, so make sure you can tell the difference. Both sounds could be caused by various factors.

Squeaking indicates that your tires are becoming worn or uneven. This makes driving in general difficult in poor road conditions. Replace your tires to improve your vehicle’s traction on the road.

5. Lubrication

The most common cause of a squeaking sound is something that isn’t properly lubricated. That something could be the suspension of the vehicle.

A simple spray of lubricant or grease from the areas where you are hearing the noise will suffice.

 6. Steering Problems

If you hear squeaking or whining noises when turning, the steering could be to blame. The most common cause is a lack of power steering fluid. It might also be tainted.

This fluid is required to lubricate the steering system. It can no longer do its job effectively as it becomes clogged with debris and dirt.

Fixing The Issues

To fix the issues causing the squeaks follow these steps

1. Brake Replacement.

If you hear squeaking when you apply the brakes, you may need to replace the pads. When metal comes into contact with the rotors, the squeaking turns into a grinding sound.

If you need new brake pads, you could spend up to $100.

2. Serpentine Belt Replacement

A serpentine belt is inexpensive to replace, but ignoring it could result in costly repairs. The belt should cost no more than $75 on average. While doing so, you may need to replace the tensioner, which could result in additional costs.

3. Replacing/Aligning Tyres

If you hear squeaking, it’s always a good idea to inspect the tires. To begin, check all of the lug nuts to ensure they are tightened. This action costs you nothing and ensures your safety on the road.

You should also check the tread on the tires. If your tread is wearing unevenly, you may require an alignment.

4. Lubricating Suspension

If a squeaky suspension is making your drive unbearable, you should lubricate it. The problem is determining what is squeaking.

Once you’ve determined the source of the squeak, apply a small amount of lubricant to the affected area. This could be one of the cheapest fixes available.

5. Replacing Alternator

To remove the alternator you should inspect the car for the codes and another issue as it may have caused due to several reasons

1. Unplug the negative battery cable. This step is critical if you want to avoid a short, which we know you do.
2. Find the Alternator. Depending on the vehicle, the alternator is mounted on the front or side of the engine.
3. Examine Related Components The drive belt should be replaced every 90,000 miles.
4. Remove the alternator. After inspecting the electrical connections, drive belt, and any interference items, remove the bolts and alternator.
5. Carefully remove the alternator and any associated wiring.


Strange car squeaks when driving are usually an indication that something is wrong. In many cases, it will be a minor issue that is simple to resolve, but it may also be an early warning sign of something more serious. As tempting as it may be, ignoring it and hoping it will go away is never a good idea. Instead, get it checked out as soon as possible.
