Our '95 SR is down because the rear diff fluid is leaking out through a weld crack. The weld on driver's side axle tube extension off of the differential is cracked about a third of the way around. It started as an annoying mysterious drip and now is an official leak.

We removed the axle with the intention of welding it up. We cleaned it up ground a bevel into it, removed the axle shaft and then chickened out due to listening to dooms dayers.

I have production weld experience but I don't know the metallurgy of the axle. It appears to be cast steel so with a little preheat it should be able to be welded without exotic welding requirement. But, I would feel a lot better if I knew that others have welded their axles with success and how they did it.

Thanks for any advice/experiences/knowledge/sympathy. I will add pictures this weekend.
