only thing that sux is if you do it yourself breaking the axle nut loose is always fun. Sometimes even with a huge pipe it won't come loose. If you know a friend or someone that has an air have them break the nut loose or do it there. If you have them break it loose just have them break it loose and retighten it back to close to what its supposed to be at. Not saying this is a great idea cause you should always have it torque'd to spec to keep it on but an axle is free floating so the nut just really holds it in place while the suspension makes its effective opporating length shorter and longer.

If it were me and i didn't have air (which i do ) then i would try a huge cheater bar or have a buddy break it loose. Drive it home, do the work, get a new nut, torque it and have a beer.
