Passenger Side Rattle.

Paranoid OCD me will be checking all my seat belt anchorages now

Thanks though for highlighting the potential safety issue.

I had an annoying rattle a few weeks ago, and identified the rear bench seat (one piece long) as the problem. When it is "stored" (flat forward) it makes no noise, but when a "seat" it rattles. So I leave it "stored" unless I am carrying some people.
