I am not sure if this has been covered before or not as I am new here BUT I recently purchased a 98 max II from my dad and decided to beef up the axles. I found that 1-1/4" sch 80 seamless pipe is a perfect pressed on fit over the outside of the stock axles. I also added 3 gussets to the back side of the flange welded to the new outer sleeve. Cheap and easy upgrade to prevent bending and breaking. No idea how to add pictures but I have some for anyone interested. Zach J.
