Ford Repair: Ford Explorer, brake caliper, wheel hub

Question
-Erik...
Thanks for your reply.  Will it be very hard to change out the bearings.  I can do basic mechanics on my vehicle.  I don't have special tools or a rack but could I do this job?------------------------

2003 Ford Expl, 6 cyl, XLS (basic Explr, nothing fancy)  I've been hearing a whurring-roar from the front of my car for a while.  Everyone said the tires are cupped.  I've replaced the tires and the noise is still there.  I suspect a bearing is bad.  Is there anything else that could be wrong.  Alignment good, tires new,  brakes fairly new...I'm stumped.

I think you're on the right track. Have a garage check it out for a bad bearing.
