Vehicle is experiencing grinding noise coming from the front driver's side wheel. When brake is applied the vehicle will shudder to a stop followed by a loud bang before completely stopping. Noise is intermittent and has occurred in all conditions at all speeds. Noise is also much louder at higher speeds and when window is rolled down. Vehicle started problem at 14,000 miles and has continued ever since. Vehicle went into the Ford service 3 times for test drives, only to leave with no resolution since technicians could not duplicate the noise. On the fourth visit technicians heard the noise and replaced the front driver's side hub assembly. They could not find the cause of the hub engaging while driving. Four days after new hub was installed the truck started grinding the hub again. Went in for 5th visit and is still in the shop while they continue to test drive the vehicle. I believe this problem to be dangerous to myself and other drivers because the noise is so loud that it is distracting to the driver and causes other drivers on the road to wave and flag down my vehicle to alert me to the noise. I also believe that the shuddering that is occurring during braking when this grinding noise is present could lead to an accident if cause cannot be found.
