Take off wheel, remove caliper, (2 bolts) and set aside. I use an old coat hanger for tie wire so it doesn't hang by the brake line. remove rotor, remove axle nut, unplug abs sensor, unbolt hub (4 bolts) and pull or pry hub out. Shouldn't be to bad if it's not all rusty or corroded.
You can use a hub puller. Harbor freight has them cheap. I use pb blaster and let soak on everything for a little bit as well.
A wood block and mallet on the axle after removing the nut can help pop them loose as well. Hope this helps.
It's pretty much the same for most any Jeep if you want to find a YouTube video, I'm sure there are a few.
