Passenger seat can rattle like crazy when no one is in it. Anchor bolts are tight. Any thoughts? I know this is a common issue/complaint. I did search this forum and didn't find anything specific to my problem. Thanks.

 

Some times I get a rattle now and then, I would check to see how far your seat is set back, it could be rubbing against the back wall. I know when I'm driving with the top down around 70 or 80 I get a rattle from the back window being up.
