Hello, our beloved 2013 VW up unfortunately has a disadvantage. For a long time we have had hinds of squeaking and cracking the feathers / dampers. I have also read it could be due to the rubber bushings. Therefore I think about changing the bushings to stiffer PU bushings. Maybe then also to change the dampers. Someone here experience / tips? I don’t want to put the Fzg. much deeper.
