Welding on Dana 60 cast housing....?
Here's a fabrication question that I need answered, as all the theory and numbers I learned in school never seems to be able to substitute for good ol' experience.
I'm contracted to design and construct suspension under my buddy's 52 CJ. W'eve managed to locate a rear Dana 60 full width axle and while Iv'e built several 2-, 3- and 4-links before, they were all with Ford 9" housings, with the 3rd member removed.
My question is this: Do I need to use a special filler rod to weld toweres and such to the cast(IRON? nodular or gray or what?) center section of the housing? Or can I just get away with pre- and post- heating with a torch? I will probably be MIG welding them, but can TIG it if necc. with high nickel rod or the like.
Anybody ever have the housing warp too bad so as to bother bearing bore alignmant or anything?
I see other people getting away with it all, but I was just curious. None of this will be repair or anything, just modification.
Thank for your opinion!
