    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?

    The motor thats going into it made 500 wheel hp in the car it came out of.
    I plan to add nitrous eventually. Auto trans. 4L80E. Drag radials.

    I found a shop that will do the welding for me. Includes welding the housing and adding c clip eliminator axle ends. Cost for the welding is 500$ Plus parts.

    Wow, I really wasn't expecting it to be that much. It must be WAY more complicated than I thought.

    What parts are extra?

    Just remember that you are welding cast iron to steel. This requires a special welding process. This is NOT something that you can do with a MIG welder and steel wire. The filler material must be compatible with both cast iron and steel, and be resistant to cracking. Most people use nickel for welding these materials. I use a TIG welder and N99 wire. There is special prep work that must be done before welding, and preheating is also required.

    These guys are specialist. So hopefully they know what they're doing.
    Parts are for the c clip eliminators and hardware.

    This isn't too bad I dont think. Everybody has to make a living. I dont mind paying good money for good work.

    I can verify that having the axle tubes welded would be a good idea i spun my axle housing on the tubes running about that power level dropping the clutch on a four speed. The housing spun upwards about 45 degrees, broke the u-joint loose, and put a hole in the floor with the driveshaft. It was cool, kind of.

    It's worth asking, even if they are considered specialists. If they do it wrong then you wasted your money. There are MANY people out there that think it's fine to weld it like it's made of steel. It looks fine, but it won't hold.

    Yes even if they INVENTED welding....."ask....so whatchya gotta do thats special with this?"...and yeah they will be sure to splain it to ya....price isn't good or bad for good work. Bad part is MOST of the time you are paying for....is cleaning and prep.

    If you were around the Chattanooga TN area, there is an excellent shop here. When they did mine, it wasn't a solid bead all the way around, but 1/2" runs, done in an opposing pattern. I'm not an expert at welding, but you can look at this and tell it was done right.
