Broom handle (or = sized dowel) sharpened to a tapered square shape holds the inner shock tube when you spin the bolt out of the bottom with an air wrench. With some help you may get it out w/o the air wrench but it is loctited when assembled so needs much power to break it loose and turn it. Special tool listed in the factory manual will NOT fit down the newer tubes and second tech schools recommended tool is only a 3/8" drive version of the broom handle which the parts guy told me about after I had purchased the 2 nd version of the special tool. Use care to drive the seal into the lower tube. I only removed one fork at a time and be careful to route the turn signal where they belong. I didn't on one side and ended up piching them between the fork stop and the lower triple tree. Also you will need a big socket or wrench to loosen the top nut on the tubes as they retain the tube in the upper triple tree. Max
