The door hinges for my driver side showed up today. The passenger door is still on the original hinges and they work pretty good other than I think the detent spring is broken but that's not a big deal. The upper driver side hinge is rusted solid still mounted to the door and the lower hinge came in a box with the pin busted off and halfway drove through. I figured where the driver side is going to be getting more used Id just put new hinges in.
I noticed both the upper lower hinges have a passageway drilled that goes all the way to the pin. I'm assuming it's a place to spray oil. Can anybody see a reason not to put a grease fitting in there and then use a long needle fitting to grease the door hinges occasionally?
