I know this has been discussed before somewhere on the site but i couldn't find it. when i turn my wheel to the left while moving at any speed, there is some kind of scraping or rubbing or it is almost like a buzzing sound that comes from the front wheel. It has gotten a little worse and i want to take care of it before it is a huge problem. I am assuming it i will start on the right wheel too or maybe it does it already and i just can't hear it. Does anyone know what this would be? thanks.
