I have been having this issue in driver front side since Feb. 2010. I’ve had the ABS sensor and bearing in this wheel replaced twice; also all 4 wheels’ brake pads, rotors and caliphers replaced; parking brake replaced. My mechanic (not dealer) is master mechanic and has 3 other mechanics in a forum…

It seems that you have reached the end of your “master mechanics” abilities. If I were you I would find another set of eyes to peruse the situation.
