If it's a bolt, you will need a torx bit, but any Jeep owner should have a set of those already. If it is the actual nut then you will need a reverse torx bit, which your local auto parts store should have. Other than that you should just need a decent set of tools. Don't forget a cheater bar, but if you have a hi lift the handle works great for that.

Gun it and run it!
