Your last paragraph is telling indeed. If the leaf springs keep the rear 
axle in line then movement up and down causes the rod to push into and 
out of the frame mounted bracket. That's what causes the flex and 
subsequent failure.  And because it is a badly located rod, it should 
actually be horizontal in its attachments, then the off angle 
exacerbates the problem of flex. Every little bump and it's rebound...
