Had to google. I guess its an axle assemble now. Hopefully you have extended warranty that will cover it. If not, I'm guessing you're looking around $700 parts and labor or so to replace it, if you allow a dealer to do the work. If you think you can do the job probably $200 ish in parts to fix it yourself.I will check again! I did just have the car in for it's 60k mile service and inspection but the Ford SA didn't mention anything.
