I just had my car at Subaru a week ago for that free April checkup and they said it runs fine, nothing wrong. Today while driving I heard a grinding sound. I had hoped it was the car in front of me but I kept hearing it when I was alone on the road.
It only happens in gear, brakes not applied. If I shift to neutral and coast it goes away.
The best way I can describe it is it sounds like a scarping sound like a penny got got on the disk, but I really have no idea where the sound is coming from (I checked the disks and didn't see anything stuck).
What's the best place to start? Axle? Engine mounts? Struts? Brakes?
