Morning everyone. I own a 06 SCAB and when I hit a sizeable bump or deepset manhole I get this rattle in my door right where the suicide door and driver door meet. I searched and found nothing, so I am looking to some insight or if anyone else has had this problem. Any suggestions would be helpful. It was at the dealer yesturday to fix the window issue and they said they didn't hear it. thanks in advance

 

Before I got to the part about the dealership and window repair I was thinking window regulator loose. Take the service manager for a ride and make him understand what you are hearing.

 

Make sure that both doors are fully latched. (2 stage latches) If it still rattles, the striker/s may need to be set inward a bit to tighten the doors against the seals. Did that with mine and cured a water leak issue at the same time.
