Just tackled a creaking door today. Took off the door panel, removed the door check. Turns out it was very dry. I lubed completely and installed it. Door still creaked and squeaked. I then realized it was coming from the hinges. I blasted both with a super silicon penetrating oil and .... the creaks and squeaks were gone. Yeah!
