AWD front diff, Broken mounting ear on pass side, Weldable?

[AltxF4]

In the process of replacing my trans I decided to attack some oil leaks. While lowering the front differential to do the oil pan gasket, I found that the passenger side of the front differential has the rearward side mounting ear broken off. I have no idea how long this has been broken, but I am wondering if anybody knows if the long tube side of the differential is a weldable alloy. Anybody else experience this brake? There was no steel saddle clamp that went over the axle tube for such a thin aluminum cast section, should there be one?

I think the brackets on my 2012 are cast iron

Well, the casting for the part in question is a little porous, and has let some oil ********* in. With that said, it was weldable. I had the AC Balance set at the limit of constantly melting my tungsten, but I had to as to get a mostly clean weld. The job is not pretty by any means, and I think I will make up a saddle out of steel to hold the differential tube in place if the ears break again.
