A creak or squeak can be heard from the top of the front or rear doors. This noise is most noticeable when the windows are fully up. The noise is caused by the decay of the flocking material on the door seals. New door seals, Teflon tape, special lube, or a combination of all of these may be needed to eliminate the noise.
