Hello all,
This morning while driving, I noticed the piercing screeching sound from under the car, may be from the wheels, metal sound like brakes to rotor. I stopped the car look at the brakes, they're all good. What can this be? Bearing? Any input will be greatly appreciated, it's 1996 A6 wagon, 144k miles.

Thanks,

Louis

Does it change when turning?
I had a squeal that I traced to the rotor shield touching my rotor. A slight bend backwards and haven't heard it since.

Thanks, I think you're right, the sound stopped since yesterday.
