You may be able to hear the front bearings while turning. They usually change pitch, or loudness when turning one way vs the other. Also, you may be able to feel the looseness/slop when the wheel is jacked up off the ground, and you rock the wheel back and forth. Turning it may also reveal some noise.
The bearings are not serviceable. You have to buy the hub/bearing assembly as a unit. I think I paid around $200-$270 at my Ford dealer. I don't recall the exact price. Not too hard to R&R. You will need a 36mm socket for the axle nut.
Hopefully, your rotors aren't frozen on to the hub. If they are, you will need a gas torch to heat it up. Heat only around the hub, not on the rotor surface. If you don't have heat, you'll likely have to break the rotor. Get a big hammer, like a 3 lb'er, and hit the outside of the rotor surface. HARD. A couple or 3 big hits should break the rotor along the top of the hat area. Don't even waste your time trying to tap the rotor loose form behind. If it's loose, you'll know it. If not, you'll be also investing in a new rotor.
