The cone washers realy aren't that hard to get off. Just use a screwdriver and mallet or something of the sort.
It makes things alot easier if you get a socket for your spindle nuts.
While you have everything apart, you might want to check your nearings and make sure they don't need to be replaced.
When you take the hub off, if you don't plan on taking it all the way apart and cleaning everything, then don't let your curiosity try to make you play with it, because it is a B*T#H to get back together.....if you feel you must , you can search for how to do it on the internet, or just look carefully how the springs go on the tabs.
Thats about it. Ive taken my front end apart about 3 or 4 times, and never changed those seals/covers on the back of the knuckle, but i should, because they do leak.
