I just finished up welding the spider gears on my rear 60. What I'm wondering is if I should weld the gears to the carrier as well. A Google search yields a lot of ugly welded diffs, so can you all post up pics of welded gears done right?
Mine is welded like so - ran 44's like this for awhile, with 37's I've killed my transfer case twice. It's a D70 though - so that could be part of it...

if you just weld the gears together, all the power is transmitted through the cross shaft. if you weld the gears through the carrier, the power is transmitted through the cross shaft as well as your weld area.
Makes sense. I never analyzed where the forces are actually going.
I'll get some pics as soon as I get to working on it again. My new Trans Am is down :mad3: so it'll have to wait til I get that going again. I'm not the greatest welder but I'm using 6011 1/8" turned up real hot and I'm pushing tons of metal in there so it should be :smokin:
When I welded the diff in my toyota third for my samurai, I welded them to the carrier. I figured why not? You aren't really gonna be able to use that carrier for anything else anyway.
Travis..

Well I think its finished. What do you guys think. Do I need more filler welds? *edit: I'm not done cleaning it up yet, don't worry, I will remove all the spatter.

You need to finish welding it with 7018 (low hydrogen) It has a higher tensile strength and wont crack as easily. Nothing wrong with what you did so far at all. Just cap it out with Low Hy.
make it one all in the same. just one bis sphere. I'm running a 60 and made it one big sphereand have broke a total of 9 stub shafts before i said i give and bought chromo shafts no problem now. lol lol
I have been a pipeline welder for a number of years now. Welding pipe to hold up to 30,000 psi involve a correct procedure. When you add stress to vibration you need to have a 70 series rod to hold it together and eliminate cracks. If you leave the 6011 alone in there it might take a year or two, or a day or two; BUT it will crack out on you eventually. Trust a guy that has literally welded miles of high pressure stuff together. 7018 is the rod you need to finish with. Just slobber it in there dont even worry how it looks and it will hold forever.

fill it in more. wish i had pics of mine when i did it, it looked like shit but i filled as much as i could and its been great.
weld the spiders to the carrier the first time or you will be doing it later
thanks for the offer xxxbronc. My dad is pretty good with a stick welder, but his advice never seems to work for me!
