I got a bad sound too
 

Scraping sound on the right side.. I think it could be my brakes..but its when I'm actually moving...I was doing about 50 today down the road and heard it for the first time.. kinda like a high pitched scrape.. I checked to see if it was my o2 sensor on the road but I don't think it is..its not long enough (the o2 sensor on my exhaust not the other half)

What could this be?

it could be ur brakes still. if the caliper isn't going back to it's "non-braking" position...does the car pull a lil bit to that side when it's making that sound?

yea i changed out my front brake pads... no more sound..i was metal on metal pretty much... any clue as to why only the right side was that way though?

brakes aren't stopping EXACTLY equal every time you hit ur pedal..just over and over and over again...
