Just fixed mine last week after using every kind of lube there is, nothing worked. I figured drilling wss cheaper than new hinges. I drilled a 2 small holes on the inside of the hinge (one top, one bottom). I used a bit the same size as the tube that goes on the WD-40. Use caution when drill, don't want to drill into the pin. Squirted the crap out of it with PB blaster and working it opened and closed, after several flushings it works like new. I then put some white lithium grease to help it stay smooth. I may put a little silicon in the holes.
