Joe,
I know that Kenny did his own bearing re-pack and he said that it wasn't tough just time consuming. I am about to tackle re-packing the front bearings and replacing the rotors and brake pads myself next weekend (to get ready for Moab), so I'll let you know how it goes. For now you can read up on the procedure in the article below from the planetisuzoo site.
