ok i was at superlift orv park and bashed my front diff on a big ass rock. it cracked and is leaking fluid out of the housong. i am going to get it welded up what do ya'll think.
If it is a small crack, you might drain it, clean it, JB weld it, fill and flush it then fill it again. Even then I wouldn't drive it offroad until I got it fixed/replaced.
I too have an aluminum axle housing (asuming that's what broke) and an aluminum third (sorry, no gears - just the housing) laying about.
pm me if you want either of them cheap.
