Rear Tailgate Ajar On Lhs ?

[Chryslernewbie]

Hi having just bought my Chrysler grand voyager I have an issue with the tailgate motor catching when I open or close I can see a small score on the side ( metal on metal )? When fully closed it pulls in to close tight but on the lhs there is a 5-10mm gap that is annoying when driving as it causes a loud noise due to being open to the elements. I would appreciate wether a slight tap to the right may help or any further assistance ? Ps the struts on both sides seem to open and close pretty good
