4 door dart innards for doors

[Cruisingram]

Both my front doors are hard to open, the passenger door I think the bushing for the rods is just plain wore out. is there something that makes some kind of restore for old mopar doors? My back door window is really hard to roll up and down, and I don't see a good reason that is happening either.

50 year old dried up grease is likely the culprit on all those problems. Remove the parts, degrease them, and use a good synthetic grease to recoat them.
