Snarling of the tailgate at V60 MJ 2013

Hello everybody, I noticed this winter that the tailgate does not use it at low temperatures and for a longer time, when opening makes very alarming knarz noises. Sounds as if Kunsstoff is slipping over Kunsstoff. I sprayed the hinges with silicone oil before, but that didn’t matter how much. Maybe someone could have noticed such a noise when opening the tailgate, and what would be even cooler, someone has a trick like that Is it really embarrassing for my ABM buddies who always smile at my elk from their full premium bodies when his tailgate is opening when jaulting. Is a moose is already clear, it just has to tubes, but maybe there is a solution.
