I have a 2009 Camry SE, I'm in the process of sound deadening the doors. I noticed a foam rounded block that is attached to the interior of the front and rear doors. Some have a plastic piece that over the foam. I needed to remove these blocks to seal the doors and apply the deadening material. I had removed some of these blocks from my 2006 access cab front and access doors. I assumed they were only for support. They looked a bit more high tech and included some plastic on the 2009 Camry. Do this foam parts have a purpose, can they be removed without affecting anything? Thanks
