1/2 ton status
well i know its been beat to death but would my half ton axles with 33's survive welded front and rear. i have a heavy foot sometimes off road but only a 250 under the hood.
Nope. They will probably blow up. And welded front is all bad....you won't really be able to turn much.
Weld the rear, run it til it explodes, then upgrade.

Should be no more stress than running a Detroit or Lock-right in them and I really don't think they will randomly explode at the first site of dirt and kill a bus full of nuns like is being hinted at above. Let's not get carried away as you typically don't need 1-tons when running 33's and a 250 I-6.
Detroits and Lock-Rights have some slop built into them and this makes them MUCH easier on shafts and joints than a spool. Basically the tire can rotate some before everything binds up, while the spool is binding everything as soon as the wheel is turned.
Longfield will warranty their shafts with a Detroit, Lock-Right etc but they won't with a spool because they kill shafts.
I disagree. The "slop" in a Detroit or Lock-right causes shock loads which break shafts. There is no cushion or anything in those that lessens the shock load, and the last time I checked "slop" causes breakage. A loose bolt with slop has a larger chance of failing them something tight with no slop. What about those stories of the loud banging and lane changing caused by a Detroit? Where do you think that load is transferred between, maybe the shafts? The same theory is also why breaking a shaft often fails a Detroit, it's just the shock load going the other way and the slop causes a huge shock load.

I knew someone would come up with that argument
In theory that seems right but my experience and that of others seems to say that mechanical lockers are easier on shafts/joints than spools.
To me, completely unprofessional knows enough to be dangerous guy, it seems like you guys are both arguing for the reasons the lockers and spools both damage stuff.
Lockers have the banging from locking and unlocking. Shock loads.
Spools/welding means the diff can never unlock and release that tension that builds up unless a tire slips and releases it. Tire doesn't slip, the twist keeps happening, something breaks.
Different symptoms and causes, same result...broke stuff.
