Not really a problem, but more so a nuisance I have.

My passenger door sounds great. The door shuts solidly with a deep thump, like that of a Mercedes or Jag.

My driver door sounds like tin when I close it. It's loud, sounds cheap, and has a bit of a rattle.

Coincidently (not so much), this is the door that has slight wind noise on the highway.

Anyone have any ideas for a fix?
