sounds like me and nickyoobatz have the same issue but at different noise levels...let me know what you come up with too
I also recommend bringing it in to your dealer and speaking to your service manager about this noise, ekopel. He is in the best position to look into this for you and can check into any warranty, assistance, recalls, or customer satisfaction programs that may apply to your vehicle.
Also, remember repairs done at a Ford Dealer come with a 24 months/unlimited miles warranty. You can schedule an appointment online here
