Hey guys, first time posting but in need of some assistance. I have a 09 f150 xlt 4.6, and I'm having problems with the passenger side wheels intermittent "wurrring" coming from the tire at all speeds, I have changed out the wheel bearing as well as cleaned the one way check valve to the 4wd actuator as well as the actuator, changed the breaks last week, and still there talked to 2 different dealerships about the issue but in not prepared to just let them do exploritory repairs till they fix it, it's become a vendetta I'd like to know if anybody has any input that can assist me.... Thx a bunch
