My targe squeaks when the car's chassis flexes. I've taken the targe apart and tightened every bolt on it and this hasn't helped. It almost seems like the squeaking is coming from the front screw areas. The weather is really cold right now, perhaps it will go away when things warm up? Alternatively, I was thinking about applying a thin layer of hinge grease to areas of the targe that touch metal to metal. Any thoughts would be appreciated.
