I did my front right outer boot back in May (and also the inner boot since I was in there). I ended up taking the axle out, which was not hard. The hardest part was trying to understand the instructions in the thread:

Yes, maybe if you can understand what they're saying, you can do it in 30 minutes, but it will take several hours of reading and experimenting to get there.
My post in that thread is #374, followed by some good info and my followup thoughts on how I would do it next time. This is one of those jobs where the right tool or something being a little more stuck vs loose may guide you toward an alternate solution that is easier. So flexibility helps. Good luck.
