lug wrench, 9/16 socket or wrench, and a jack. I think thats all i needed when i did mine before I moved. Very easy, nothing to it. Pull the tire off, loosen the caliper, pull the caliper off, pop both pads out, put grease on back side of new pads(optional), put new pads on, put caliper back on, put wheel back, test drive. You can look at your rotors during this process, I replace rotors and brakes at the same time though. You don't have to if you feel they aren't that bad, or you can just have them turned if it's slight.
2004 Wrangler X, 31" tires and new bumper. More planned for after I move cross country.
