Here's a picture of the weld on the axles that supposedly was going to hold them together instead of the pin (which is in upside down in this picture...) The weld is broken and I hope to just grind it off and ignore it...

Allen, when you grind the weld off, you may find that the holes in the inner axle tube are elongated and worn.

They are for sure.

Is there a fix for that?

You can weld them up and re-drill them or replace the inner axle tubes.
