jfonod -> RE: Side door hinge issues (11/17/2007 8:15:17 PM)

The problem is corrosion/seizing of the hinge pin. Acutally the problem is a really crappy design from GM. The GM "fix" to this is to drill a 1/8" hole the middle hinge section until you get to the pin (I prefer 2 holes, 1 near top 1 near bottom). But anyway, the basic idea is once you have the hole spray a good penetrating lube equipped with a nozzle straw into the hole and soak the piss out of it. After letting it soak in, gently move the door back and forth until it frees up. This could take a couple days of doing depending on the situation. THEN, you want to lube it again with say lithium grease again thru a straw for a lasting lube. Some folks even silicone the holes when done. If you have a nice van such as a conversion and don't mind spending some dough, you can have a body shop remove the pins and replace with stainless steel or even clean up and grease the originals. All I can tell you is, I have been working for days to repair a broken hinge I have in lieu of a grand to have a shop do it.
