They don't come out easily unfortunately. What I like to do is spray a little WD40 around the creases of the Center cap and take the end of a hammer and push it out from the inside of the wheel. I never tried it on the Jeep but I have on many GMs. It may need help from a flat-head screwdriver to pry it out from the inside. If you pry it on the outside, you will definitely nic up the wheel.
