If you dnt have a repair manual, i recommend getting one. Other than that make sure you have all of the tools, repair parts on hand and grease for new bearings. Other than that, take your time and plan for it taking alot longer the first time than expected.
Rock Auto is where I got my parts. Calipers have to be removed to get the hub assembly off. Bearings only are pretty simple. If you replace the bearing race(s), they need to be punched out from the backside. You will find 3 slots machined into the hub. Using a copper "drift" and hammer start working equally around the hub. A regular race removal tool with the disc's that attach will not work on these. A good repair manual is essential.
I did mine without a repair manual, but it's nice to have just in case. Once you get in there to start, it's pretty obvious what needs to be done.
