Does anyone else have window seal rattles this bad?

I noticed this shortly after I bought the truck, and it seems to have only gotten worse. It's caused by the seal itself tapping against the metal section is sits against, not in any way by the window glass itself.

Here is a video of me driving down a smooth highway:

And here's how bad it gets on gravel:

A short term fix (literally hours, or until I get on gravel) is lodging some WD40 Lithium Grease into the space circle below. That hard plastic weather stripping right there is the culprit.



The nonstop clicking is definitely annoying and makes the truck feel cheap. The dealer said they could be replaced for $200 per side - might that be my only option?

 

No noise from mine. If you could get some butyl rubber sealant under there without making a mess it may work, but you'd need to clean out the lithium grease first somehow.

 

Bump?
