What is this terrible sound coming from my rear axle?
 

I noticed this sound on my trip for Alabama to Ohio last week, it is extremely loud. I have determined that applying the brakes/emergency brake makes no difference, nor does being in gear. I believe it is coming from one of the wheels and not the gears or transmission. I do not see any fluid leak from the axle.

When the recording starts I am in neutral at 70 MPH, gradually slowing to a stop. The same noise can be heard during acceleration or while driving at any speed. It gets louder as I go faster. What is causing this noise to come from the rear of my car?

More than likely a wheel bearing I would think.

Is it bad to drive on? I'm pretty sure I've already put hundreds of miles on it while it was making this sound

If it locks up it could do some damage..better to have it checked out sooner than later.

The dealer can't get to me until next Tuesday. I don't have another car or way to work, so I hope it holds up.

Now they're telling me that it's not covered because my bumper to bumper is up... how is this not drive train?

tell them to get on the ford site and run the base part number for the bearing for approval, and then print out the sheet saying its not covered, if they wont then they are full o crap, i rebuild rear axles under drivetrain warranty all the time

Yea I called a different dealer and they confirmed it's powertrain - PHEW... The girl at the other dealership apparently doesn't know anything. Guess I'll wait until Tuesday and try to keep the miles down

the funny part is there is an online tool on the ford site to take the guesswork out of warranty claims, you input vin#, mileage, state, and base part # and bingo instant approval/denial. seems like she has never been trained.

I jacked my car up last night and recorded my wheels moving. When I tried to jiggle the wheels there is a very slight movement, definitely shouldn't happen.

The video below speaks for itself, both wheels look like this. Please tell me it's wheel bearings. I really don't have the patience to fight Ford on their ****ty quality. I baby this car, I have not wrecked it or abused it. I'm about to cut my losses with this vehicle and never buy another Ford again.
