Did anyone with a rMBP had a similar situation? Creaking get worse especially when the unit warms up, and is caused by wrong/to long screws and/or damaged screw treads in the case.
I finally received the pentalobe screw-driver, however for some odd reasons the screws at the middle (at the air vents) are to long and can't be further screwed. This cause the whole unit to flex, hence the loud popping/creaking sound. See also how misaligned the bottom-plate is. It also seemed that by manufacturing the thread in the unibody aluminium is broken.
