Trunk squeaks very loudly and after having lubricated all the hinges and joints, it seems that the noise is coming from within the trunk door and not the trunk compartment. Does anyone knows whether there is a hydraulic strut to be replaced? Or is it just simply a spring? The noise is absolute madness as can be seen from the video.
