$4 flat pry bar from Harbor Freight. Just work it around the the outside of the hub cap. Pay attention to the center cap...it will come off with the big outer ring.Yes, I finally figured those extensions, and they work. I am using the Milton as well, still a pain but it works. How do you pop off the hubcaps? by hand, crowbar? Specially those rear tires. It can't be that hard or they would never sell a Dually lol.
