i was wondering if there is any way to beef up a stock axleshaft. obviously the number one failure is breakage in the splined area due to a score line that is created by the mating splines. would a simple debure of the female side solve the problem, or could you go as far as to have the axleshaft hardened. the reason why i ask is im putting 500 horse to the truck with 4.56 gears. any help would be duely appreciated.
