does anyone know exactly what kind of steel the rear akle is made of as i was thinking of welding some trusses to it as my tracker is frequently airborn and i am worried about bending it i am eventually going to swap to a ford explorer axle with disk brakes as i can put an ox locker in it with a pull cable to engage it instead of the unreliable air locker systems. but i don't have the funds right now i figured welding the housing would be free and easy as i have literally tons of scrap steel and a welder and torch.
