    How do I fix this leak?

    D44 pumkin is leaking at one of the weld spots that holds the long side tube in place. What is the best way to go about fixing this? Should I take it out of the EB to do it? Guidance Please... Thanks.

    Looks a little wet around the whole tube...? Hose it down with some carb cleaner to clean it and dry it up. Make sure it is just that plug weld.
    If it's just the plug, I would weld it right where it sits if it were mine...

      It has been cleaned, and yes it does look like the tube is seeping/leaking too.

        If you are a decent welder you can get it right there. If your a hack, its a lot harder to weld upside down, get a buddy.

        Just grind out as much as you can, asn re welded.
        Sadly, its leaking because something moved. I would also weld all the way around the housing/tube as well to keep it from moving again.

          The best way to fix it is to swap in a D60!

          As mentioned above, I would re-weld the rosette weld and weld all the way around the tube too. But to weld all the way around you will need to preheat the area first, then weld it and let it cool down very slowly. Otherwise the new weld will just crack. Now to do this operation (you gotta love the snowball effect) you will need to take everything apart because you will probably melt your inner axle seals.

            So when I take it appart to change the gear set and put a limited slip in it, I will have some extra work to do...

                THAT will be the perfect time to do it! Nice timing on that one.

                  Doug, I'm in gthe same boat with the Teal bronco. I was thinking about having Brett weld the tube but I hate to tear it all down. I may just live with it for awhile.

                    Clean it, slather it in Right Stuff, and do some tack welds on the tubes. It would last awhile before a full teardown. My .02

                          Re: (Need to) How do I fix this leak?

                          So I am bumping this up...

                          I am at the point where the leak leaves a dime size puddle after every drive, so I need to fix it. Local Fab shop said bring me the housing and we will tig weld it up, hour or so labor. I will be going through the pumpkin with 4:11's gear change and possibly a locker ($$$)


                          Or do I buy the 76 D44 that Pops has 4-sale and build that one and do a switch out?

                          Will the repaired D44 be better than new after welding or is an undamaged one better? Certainly cost is a factor, and I do not like doing things twice...

                          Guru's please provide guidance

                            Have it welded.
                            Its leaking because it once moved. If you are not wearing tires funny then it did not move far.
                            Really most axles should have the tubes welded, so even if you bought a new one, I would still suggest welding it.

                              All the rosette welds are cracked, the time and labor needed to make the repairs exceeds the cost of finding another housing... (One dremel bit and one Mill bit already broken) The PO must have wacked something good!

                              Two Fab shops here in town said no to welding the tubes to the housing, no previous success trying to fix others with the same problem...

                              Looking at my Options...
