2003 Chevy Impala: Rythmic Screeching

Maintenance/Repairs
1

Hi all,

I have a 2003 Impala which recently developed an intermittent squeal/screech. The screeching is rhythmic and speeds up with the car’s acceleration.

What makes this interesting is that the screeching goes away when I turn and comes back when straight.

Pressing the brakes has no effect on the screeching - it happens with or without them applied.

Lastly, I want to emphasize that the noise it not grinding like most wheel bearing noises. It almost sounds like a belt squeal.

Thanks! Let me know your thoughts and if you need any more information.

Power steering belt is suspect.

Is the power steering fluid at the right level?

Sounds like the squealer that is installed on your brake pads to tell you when the pad is worn out. Get your brakes checked.
