Spring 2011Hatch deadening and closed cell foamDeadening and CCF in the hatch. I added about 10-15 pounds to the hatch pieces during the process. Basically the idea here is to add the deadener to add mass and keep rattles down. The closed cell foam pushes on the panels to keep them from rattling on each other even more. While I was in there I tightened up the clips so they hold the trim pieces as tight to the metal as possible. Here you can see the basic ideas of the process. I got in a grove and forgot to take pictures of the last pieces. Over all it took about 2 hours to disassemble, deaden, spray, apply CCF, and reassemble. To take apart the hatch you remove the two screws from the bottom of the lift gate near the handle to pull the hatch closed. Then you just pry off the top piece, then the side pieces, and then finally the bottom half comes off. They are all connected via metal retaining clips.
