well here she goes.....
1. pull the third out
2. pull the carrier out
3. pop the ring gear off
4. brake clean the piss out of the carrier(you want all the gear oil and
any oils OUT of the metal)....see if you can find someone with an old oven, n leave the pregnant dog in
there for an hour or so at like 400, that'll boil the oil out of the pores
5. then use a 1/8" E7018 stick rod(you wanna use this rod cuz it has a substantial amount of nickel
in it)...or if you can get nickel rods off someone or even buy em, run around 80-95 amps
you'll want a rod high in nickel, since the carrier is cast
6. then while its still hot(gotta weld cast while its pre-heated), just weld the spiders to the carrier,
and weld the spiders to the center pin... and since your re-heating the center pin(which is
already heat-treated, you will want to cut some piece of 1/4" plate to fit in the little windows
on the sides of the carrier to tie the sides of the carrier together(in case the carrier were to
crack, the plate will keep it together.
7. just make sure you keep everything hot while you weld on it, try and control the heat in the
carrier too, cuz if it gets too hot then it'l warp the ring gear mounting surface, then once your
done welding it, keep it some where it'll stay warm for a while and
that it takes a good 3-4 hours to cool down.... cuz if it cools off to fast, you'll have a

load
of subsurface cracks inside the cast, then when she gets torqued hard enough,boom!!
8. once its cooled off completely, you might have to do some clean-up so the ring gear will fit back
on....
not alot of people take their time when welding diffs, but if it's your only vehicle, that you drive
everyday, then do it right the first time.... then have fun destroying tires!!! haha, you'll get annoyed
after a while of it CONSTANTLY scrubbing, around EVERY corner.... and parking lots on warm days, haha,
prepare for a ton of people watching you park.... cuz your gonna be squeelin allllllll the time....
Some people may disagree with the ring gear removal, but its a whole hell of a lot easier to clean the spatter out of it when the ring gear is off.... and also spatter hitting the teeth on the ring gear will cause tiny stress fractures in the already heat-treated metal... might not sound like much, but after a while, it could cause a failure
ENJOY!!
