O.K., I've got a front door hinge on my 68 Caravel that is extremely noisy, notwithstanding all sorts of attempts at lubricating it (e.g., 3-in-1; Liquid Wrench; and, or course, WD40)....when you open or shut it, you expect to see Herman Munster appear at the door... it's that loud and creepy.... Any suggestions on quieting this thing?
