Great info, Jim...

I'm sort of thinking out loud here, since this is a fairly common 
coupe/UrQ issue I think (saggy doors).

Knowing exactly how that pin is installed helps attack replacing it, 
which of course is the right way to fix the problem (my washer solution 
was because that pin looked permanently installed).

In terms of pounding the old one out, I would worry about straining the 
sheet metal the hinge is welded to.  I wonder if it could be "pressed" 
out, somehow?  Either a small hydraulic rig with "C" shaped jaws, or 
maybe even a carefully set up "C" clamp could generate enough pressure? 
  That way the mounting welds would not be affected.

I would love to see pictures of any various stages of this process being 
done - especially if it ends up working properly!
