Yeah, it's a 2-person job ideally.  Buy a big wrench, no torque multipliers. Some buy extendable ones to make them more transportable. After that it's just a case of break it, remove wheel, clean surfaces, regrease mating surfaces with special grease, put the wheel back on then torque it. Back off 180 degrees, torque again, and jiggle the safety lock til it's popped out. Simple! 

Inspection calls for checking the mating surfaces for scoring, and full disassembly of the nut, cleaning and regreasing the internals. This can be left til service time though.
