This picture it's only about 3" from the end...this axle was originally drums.

Can I simply grind the welds on the back side and re-weld this flange further back? what are the risks I run into if I do that? I only have a 110v mig welder with flux core wire (I know, I know, I need to get it set up for gas, but I haven't gotten around to it yet, and so far, ugly splattery welds have not been a problem because I haven't done any body work yet)
