The nut that secures the bolt to the bracket will no longer hold the bolt tightly and thus a rattling tailgate ie. threaded.
Not sure how well secured that nut is but knowing my luck if I try and use a tap and go one up the nut will spin.
Couple of pics to understand what I mean.
The offending nut I have carefully highlighted with the skill of a 6 month old finger painter.
Sorry for the poor pics for some strange reason the sun is visible.
