After having trouble figuring this out I finally had an epiphany. The attached video is pretty crappy but searching the web, there's not too much good advice on this. Over on Pirate, one guy said "unbolt the wheel, take off the wheel, pull out the insert. What the problem?" Other posts use a tree or pole and a truck to pull out the insert. That would be great except when I take the wheels off my jeep it's really hard to get traction. So here's what I did.
