No big deal once you've done one...the first try is the hardest, after that, it's just procedure...
My Dad's '76 still runs the factory setup and has only had those bearings replaced once, although I do hit 'em with some grease every oil change.
FYI NAPA sells a complete unit...rotor/hub/bearings, bolt on replacement for these trucks. I haven't ever used this setup, but came across it on the NAPA online website after I did a set of bearings on a friends '77 W100. That would have been much easier (his needed the rotors replaced as well).
Good luck!
