It is a 2000 Sport, new to me with 60KM. The rear hatch was squeaking initially. Adjusted it and also adjusted the plastice piece with the small spring on it. That noise is gone but it still has a faint rattle when you go over the minor road bumps. Can't narrow it down to an exact part but I know it is the rear hatch because if I loosen the 6 nuts and readjust it the noise quality changes. Is this standard on a Dodge? Any DIY ideas on how to troubleshoot?
