when turing right i hear a grinding sound coming from the front right wheel. i first noticed the problem leaving a parking garage a few months ago. i didnt think much of it and consulted a master tech who told me not to worry about it "its probly a rock stuck in there". i was driving with the windows down yesterday and heard it again on a fast long right off an exist ramp so i went to a parking lot and it only did it when turning right no noise when turing left. also the noice it didn't happen every time i turned right just sometimes. any one out there have an idea of what i may need or if it really is nothing?
