i have a bad wheel bearing(i think) on my 06 f150. how do i get the axle nut off. i can't even see it. i've had the rotor off and all the mounting bolts out. i can pull the wheel assembly out so far but can't figure out how to get to the nut. on our 02 expedition it is right there, exposed, but this 06 has only a small cap that can't be big enough to cover the nut. what is this cap, how do i get to the nut,and also do you know what size socket i need. thanks.
