Big job? Got hubs?
Just need the right tools.
Pull the caliper off (crack the hose first...and I'd do hoses too), spin it off, thread the new one on so it doesn't leak, tie it up with wire outta the way.
Hubs/caps off, I think there's a c-clip on the axle, yours should have a 4-slot nut, use the proper tool, remove, pull the lock plate, pull the second nut?
Been a while since I did one, if you get it hub and all, easy from here. If not, use a brass hammer on the end of the studs, hit that with another to knock the studs out (I don't think they're swaged), sand the back face of the hub clean, lay the hub face down, lay the rotor on it, drive the studs in, secure them TIGHTLY with the lug nuts on backwards (with washers) and have them surfaced/turned/trued.
I'd have to look it up, but it wasn't a big deal.
