I am hearing a high pitched rubbing scratching sound when the vehicle is in motion on drive. No other sound on idle or reverse or neutral. Checked the tires, belt and pulleys, radiator fan, brake pads and rotor disc. No sound from these areas.

Hi and thanks for using 2CarPros.

My first two suspects are brakes and or wheel bearings.

First, drive the vehicle and see if applying the brakes changes the tone or sound of the noise. If it does not, find a safe place where there is no traffic. Drive the car until you hear the noise and then turn left and then right. See if the pitch changes when turning. Make sure not to be driving too fast when doing this. I do not want you to lose control. LOL

Let me know the results. Also, if it changes when you make turns, let me know which direction you turn when it gets louder.

There are warning sensors on the brakes that are designed to make a high squealing noise when the brake need replaced. And here in SW PA, wheel bearings are also a common issue which can cause such sounds.

Take care,

Joe

I recently inquired about the scratching high pitched sound and I got a reply from Jacob.
There is no add on sound when I turn the wheel right or left. But the sound is still there on and off intermittent however when I step on my brakes the sound tends to quiet down. I have recently changed the brake pads and I am out of options as I have had everything else checked except the wheel bearing. Is this just one side or both sides?
Please help, thanks.

Good afternoon.

When you press the brakes, it takes some of the pressure off the wheel bearing. That confirms the noise as the wheel bearing.

I would replace both front. If one has failed the other will be close behind. This is being proactive.

The spindle will have to be removed and the bearing pressed out and in.
