While there is no reason you can't do this job yourself, Dan...seems that it would be wise to get a bit of help from a friend or another John Dee'r who has the right tools and confidence to get this done right the first time.
There are some right and wrong ways to do this, as you can see from VETTE, who clearly knows what he is talkin about...it sounds like you might be a bit limited on tools and/or knowhow to get thru this.
Reminds me of the time, a front axle went out on me in far northern Ontario, back down deep in the woods, hundreds of miles from tools or dealer.
Having never done this before or even knowing this could happen, I proceeded to take that whole front axle assembly apart on a GM truck(short one 17 mm wrench) and was able to get it done, in the rain, while it was 36 degrees with numb fingers, and get the truck out of the quagmire, and 500 miles home, without 4 wheel drive..and minus one axle shaft, where I got the scoop on the axle, and repaired it only to have the other one go bad a few months later (ah, but I knew exactly what to do on that one, don't yah know....).
You would be surprised what you can do when you absolutely have to, but remember that it is always better to take a friend who has been there before on this ride, so that you can save some time and aggravation.
Good luck with this project.
