I've been thinking about beefing up my axles. I have a 86' Cherokee with the Dana 30 in the front and a Dana 35 in the rear. I was wondering if there is a way to beef up the axle tubes and differential. I know you can purchase new and stronger axles and gears but I was thinking about trying something to strengthen the outside of the axle to prevent flexing in the tubes and differential housing. Is this a bad idea or is it possible?
