I know the bearing is going bad again because I started to hearing the humming noise last night. But what I really don't understand is how they tell the front hub is shot also.
I just looked at fordpartsonline.com's illustration, and the front hub seems to be the piece that goes on the top of the strut right below the strut tower. I hope they mean the steering knuckle instead. The knuckle isn't that expensive, only about $130 (and hopefully include the wheel bearing).
