My preferred method is to remove the four bolts that hold the two A arms on (14 mm where the A arms attach to the frame) there will be plenty of play in the assembly to move it out of the way, give the axle a good yank and it will come out of the front differential, for the outside boot (I have never gotten one of them apart with out destroying it) I either purchase an over the joint boot (very cool, it just stretches over the entire joint [follow directions exactly, turn it inside out before stretching it over the joint, once on the axle you will then undo that process so it will be on correct]) or replace the inner one too, it can be taken apart easily by removing the wire retainer just inside the joint, there is a clip on the end of the shaft that holds the bearing cage on. Install the outer boot by sliding it down the shaft and on the joint and work your way to the inner boot and close it all up. Don't forget those two clips that hold the inner one together.
