Ladies and gentlemen, my high recommendation to get it replaced at Ford dealership. I have three mechanics and none of them knew what the heck is going on with this. $400 including parts and labor at Ford. It's not worth saving $100 at a private mechanic. Ford has changed it so many times, they know what's going on. I changed it at 60,000 miles, but should've changed it at 55,000 miles.
I changed the rear left and it drives as smooth (of course no noise) as an electric train. Bad bearing were so bad that it felt like a chopper was hovering on top of you! This is a Ford Edge problem for sure and it's super common but leaving it will not solve the problem. Another problem is the rear turn signal or brake bulbs! I've changed over 8 in 2.5 years! Next time will try an expensive brand. Moisture entering the rear lights is the problem. First Ford I bought and will never buy again.
Also, the oil change at Ford is worth it. Just keep changing at 3,000 - 3,500 miles. I don't trust the 5,000 - 7,000 miles suggestions. Thoughts?
