So I'm in the process of rebuilding my 8.5" 10 bolt for my 78. The original housing they dont completely weld around the housing where the tubes mate. I've been told its a good idea to have the tubes completely welded all the way around. My welder is not heavy enough for this type of welding. So I called a rear end shop and they said they dont recommend welding the tubes. They said it will likely ruin the housing. I question that, but I dont know. I just know what I've read and it said the tubes should be completely welded. I spoke to a welding shop and they said they would be glad to do the work. I just dont want to get left with a junk axle housing and throw good money after bad. For the record I actually have 2 separate housings. So if I did ruin one I still have the other. Is it worth doing or should I just not worry about it?
