Repairing cast steel using a mig welder is difficult for professionals to do safely. Based on your above comments I'm guessing there is no dana 60 knuckle, but rather a dana 30 you are trying to fix. Post a pict of the damage, and you will receive better information on how to repair the damage. If it is just a dana 30 knuckle you damaged, it would be easier to just replace it with a junkyard one. They are plentiful, and cheap.unclegreaser said:i need to weld a repair on my d60 knuckle and need info on which wire, to pre-heat, and other tricks to make it stong?
i have a 220 lincoln mig welder.
also is the knuckle on the d30 the same material.
Even WB has tried to weld together broken D60 knuckles on the trail and they were broken again with in ten feet. It just does not work out. I really would not do it for a safety related item like a steering arm mount.jeepboyben said:If you are dead set on doing this, I'd pm welderboy on this site, and ask how to do this.
