Rear doors squeak when opening...

and not like a " lube it a little " kind of squeak, because i've lubed the hinges with everything i can find in my garage and it still squeaks horribly every time you open the 2 back doors(not the back hatch, but the 2nd row seat doors) anyone have this same problem? is there a special lube I should use or what. its pretty annoying

it is a 2001 yukon slt

The oversized weather stripping is often the culprit. Try putting some silicone or other lubricant on the rubber...see if that helps.

Mine does it to. The squeak comes out of the slide that goes into the truck but i cant stop it either.
