Help needed--axle support tearing loose

[JimF]

I am not sure I would pull with it in this condition, hope someone comes along that can give you an expert recommendation. Sorry for the troubles, the roads up there must be rough. Good luck with this.

After looking at this crack again (third time) it dawned on me that there is rust in the frame crack, this is not a new frame crack, you have had a problem here for quite some time and the stress finally overcame the tensile strength of the frame member.
