It sounds like two metals scratching with other.
Something like KEEEEEEEEEEEEEEE~~ in very high notch. It's not very noticeable from inside, (well.. I did dynamat my door, floor and trunk) but when you open the window, it's VERY annoying. Especially when the sound is bounced back by a wall or something. It does not make sound when I'm standing still and going in a slow speed. It starts when I'm going 25+ mph. I sounds like something's scratching my rotor.
Anyone have any suggestion?
oh yeah.. I'm about 500 miles past the 30000 check up. I have to do that soon.
