Squeaking sound when driving

Hi,

Is the sound only heard when driving (moving) or could you be parked with it running and still hear the noise? Also, is there anything you can think of that makes it worse or go away?

If it is possible, please record the sound and upload it for me to hear. I can usually identify things easily that way.

Let me know.

Hi,

Are you sure it is related to the belt? If you only hear it when driving, I would first suspect something with the brakes or wheel bearing. Does the sound chance when the brakes are applied or when you are making turns?

Is it loud enough to record? Also, if you place the vehicle in neutral and slightly rev the engine (car not moving) do you hear it? If the belt is still making noise, you should. Let me know. Also, you could even have a bad bearing on one of the belt driven pulleys.

Let me know.

Hi,

Does it change when you apply the brakes or make turns?

Then the noise is brake related. Check the brake pads to make sure they are good and the warning sensor isn't touching. Also, there us a backing plate behind the brake rotor that can rust, get dirt behind it, or even get bent. Make sure it isn't touching.

Let me know what you find. I can help more once we determine the cause. However, based on your description, I am 99% confident it is something with the brakes or brake assembly.

I attached two pics below. You need to remove the tire to check the brakes. In the first picture, I highlighted the area that you look through to see the pad thickness. In the second, I highlighted where the backing plate is located. What I would suggest is to turn the rotor when the wheel is off to see if you hear a rubbing sound. Also, if you look at pic 3, it shows the difference between a new and old pad. The item I circled is the sensor that is made to rub the rotor when the brakes wear out. It touches the rotor and makes a squealing noise to warn that the pads need replaced and to prevent you from damaging the brake rotors.

I will watch for your reply

Take care,
Joe

Hi,

Anything is possible, but since the sound stops when you apply the brakes, in most every case, it is brake related. Have you checked to make sure the pad sensors aren't touching? Also, have you checked to make sure the backing plate behind the rotor isn't bent or rusted and touching the rotor?
I wish I could hear the sound. It would make things much easier for me. Has it gotten worse to a point you could record it? Also, I know it stops when you apply the brakes. Does it change when you make turns?

Joe

I feel really bad, but I can't hear any difference from driving and braking. Have you tried lifting one wheel at a time to see if there is a noise if you turn it by hand?

Joe

Sounds like a plan. Let me know what you find.

Take care,
Joe
