ok, i read the article and I think I see why you cant change the axle as an assembly with this method, because i assume the green part, or the outer Cup thingy would have to come out also.

great idea, but im having problems seeing how to do the outer boot, as that is the one thats ripped on mine. He pulled the inner and swapped the boot by lowering the spindle to give him room, so why couldnt you just pull the rotor and hub and then swap the outer boot without even having to pull the inner boot?
