I can't really know for sure what you have, but my experiences with mine, after the 3rd set of bushings in a year, I looked at the oblong holes in my hinges and tried to add some nails to hold the bushings to one side and then JB welded everything in place, that lasted about 6 months. My last fix 2 years ago was to take the door off paying close attention as to which way I needed to offset, drilled out the holes oversized and installed grade 8 bolts and nuts, no bushings or pins. I actually went a tad too much and have to slam the door with a slight downward pressure. So I can understand why someone did what the did. I'd try twisting with vicegrips or a hammer and chisel to break the welds.
