I e-mailed my local ford dealership service dept. and asked them about changing out my gears, because a guy from canada had his changed out at his local ford dealer for about $200.00 U.S. dollars, which was about 4 hours of labor, not a bad price. So i e-mailed my ford dealer about changing my gears, well later yesterday the dealership mailed me back and said,"we can't change your rear gears because of E.P.A GUIDLINES and Regulations". I've never heard of such a thing, has anyone else?
