i think that's basically it (see below though)(no wheel at first.. it only gets in the way - it's a bit of a hassle) also observe the little wheel's direction of turning to make it spread out before you put the drum back on.. they are self adjusting from then on.. when you are done back up and brake semi suddenly (that's how they adjust)
definately use brake cleaner of some kind (non chlor. is good) don't loose any of the springs, washers, etc.. do one wheel at a time so you have a backup reference, just in case... i tend to use a pair of pliers on the whole thing.. vice grips grab nicely the large springs which ican a bit of a pita to get on and off.. but not too bad.. take your time and enjoy.. you're saving over $50...
(from above: you might as well check other components while you're there... CL, TREs, BJs all 3 for looseness, CV boots for tears, if the locking hubs haven't been serviced in a while do that, same for bearings.. )
