The axles for my swap are in disrepair. They seem to be in good shape as far as being tight but the boots are torn. I know they will not last like this. While at Auto Zone the other day I seen new boots. Are these a pain to put on? Do you need a special tool to put the bands back around the boots? Would I be better off to run them untill they knock then buy rebuilt ones. Also when removing them I may have seperated a knuckle joint is this possible? The boot seems streched out and will not slide back in place. I'm in my 30's and my hair is thin I can't afford to loose any more!!!!
