In my experience the hinge is likely to be bent. Pull one off. If you have
flats and a lock washers then you definitely have a bent one. They should be
installed with a lock washer only. Take the hinge and put the bolts in with a
flat washer under each one. (this simulates a compressed lock washer) Close
the hinge and the 8 bolts should be even head to head. If the bolts away from
the pin touch and leave space between the ones near the pin then the hinge is
bent. You should be able to look at it and see that one side has a bit of a
curve near to the pin end. Heat till it starts to turn red then squeeze in a
vise to straighten.
In any case I'll drag down a hinge or two from the attic and take a look
at the pins.
Our door hinges just are not very strong. Leaning on the door when it is
open is a bad idea.

Keith, I too am interested in hinge pins. My drivers door sags just a bit,
I am quite sure it is the pin, not the hinge.
