Has anyone found a way to access the inside of the body skin for the rear quarter panel? I've sound deadened the doors and hatch lid, but those quarter panels rattle something awful! I looked around under the removable cupholder / storage tray on the left side over the wheel well, but don't really see any good cutouts to reach in and access the backside of the exterior skin.

 

Yeah I hear yah. My 2009 H2 Lux has the same type of pop out cup holder. There is some sound type mat over the wheel well. But just a small strip of it. No way can I get into the rear 1/4 below it. Also the Jack is stored back in there also. Not much room.

The passenger side rear wheel well forget about. There is the plastic Housing trim that has the rear A/C unit in there. I have no clue how you would get to the inner panel's to do anything.
