Welding up LSD.

Welding up LSD.
So I destroyed the 8.8" in the truck. I pulled 3 clutches out along with a handfull of what remained of the spiders when I pulled the cover. I'm just looking for a quick fix. I know how, I know what can happen and the "fun" to be had in foul weather that comes with welding one up. But I have never welded a factory L/S. Anyone running around that was to cheap or poor in my case to fix it right? Just wondering before I take the plunge and "ruin" my carrier.

I've driven many vehicles with spools on the street. The rearend is locked now with all the clutches wacked up. But i'm not worried about street driving. I'm a mechanic the shop I work at sells tires so i'm not worried about a little tire wear. I just need the truck for the winter. It gets a locker and new gears with the new powerplant but that will not be ready before spring. I just wanna know IF anyone has a welded up LSD.

in an old 75 f250 i had back in the day the front diff in it gave up the ghost. i got a new traclok and gears for it to give me a nice posi up front. when you hit 4 wheel you want stuff to spin. when i tore the assembly down i found out a previous owner welded the carrier and spiders up in there which is what caused the failure. i found gear teeth missing, the carrier grenaded, and the inside of the housing being ground up from the cracked carrier making contact with it. my advice to you??? fix it right or it WILL cost you more when you go to replace everything in 7 months in the springtime.

It sounds like you are well aware of the downsides to running a welded rear end on the street so I'm not going to say anything about that.
If I read correctly, you said the spiders and clutches are grenaded right? You'd have to put spider and side gears in it, plus clutches probably just to get it structurally sound enough to weld. That's assuming the carrier wasn't damaged when everything went south. The other thing I'm not sure about is whether or not you can even weld a stock LS diff?? You could obviously weld the spider/side gears together, but usually when you weld up a diff you weld the backs of the side gears to the carrier and I'm not sure if you can do that with the clutch packs behind them. (i can't remember exactly what that area of the diff looks like right now to be honest) Even if you can, I think you basically have to rebuild the diff (spider set and clutches) just to get it to the point you could weld it.
Used carriers are cheap. I'd just put a used carrier in it in the meantime until you are ready to build it.
