Not to be a Debbie-Downer here, but after watching our techs, good experienced techs, replace many sets of these, I would not even start to attempt it at home. Now, if I had a good lift, a real torch, the correct tools, and an unlimited time frame, I MIGHT think about it.
I've seen them come right out and be a perfect install and I've seen them have to beat, heat, spray crazy amounts of Kroil, and beat and heat some more for a couple of days to get hubs out. We even bought a $400 75lb slide hammer tool that I still don't think really helps.
I've seen a green tech that had already do 3-4 sets install a new set wrong that would bind the steering up when turned hard.
Sorry, it's just one of those things like helping you pull a tooth that I don't think I want to try at home. Sure, I could do it, but I don't think you or I would like it at all.
