While driving on local road heard a noise from engine compartment, lost power steering, battery warning light came on and shortly after car stopped running. Found accessory belt detached from pulley. Found out from Ford that this was the crankshaft pulley, and this is quite common on the 4. 0 v6 engine.
Lost power steering when belt came off. The harmonic balancer separated with the pulley part moving 1 1/2" toward the motor taking it out of alignment with the rest of the belt.

The contact owns a 2005 Ford Mustang. While backing the vehicle up she noticed a banging noise coming from the front of the vehicle. She exited the vehicle to look for a failure but did not notice any so she proceeded to her destination; however, noise became louder. When the contact reached her destination she discovered that the crank shaft pulley was laying in the frame of the vehicle. The vehicle was taken to a local repair facility and a mechanic stated that the serpentine belt was damaged and was no longer on the pulley. The vehicle is being repaired at a cost of $700. 00. The contact is in the process of notifying the manufacturer. The failure and current mileage was 74,000.
On Saturday April 18, 2009 my daughter called to say that her car was hard to steer. She pulled over and her main belt had come off, which in turn caused the car to overheat. Upon further investigation and turning the ignition over, the belt fell off again and so did the pulley on the harmonic balancer. We had to have the car towed to a shop. Upon arriving at the shop I was told that the harmonic balancer broke off the crank shaft. When the new part arrived you could clearly see that it has been redesigned. We paid $600 to have the necessary repairs done. I was told by our mechanic that he has never seen anything like this and there should be a recall on it. I hope this will make that happen.
