I have an '05 that rattles so bad I'm about to go insane. My rattles come from the rear tailgate area and are inside, I have checked the tailgate struts and they are not the cause. I have obtained instructions for removing the rear plastic trim pieces, I have taken off the interior upper tailgate pieces and the rattling has reduced by about 20%. I was surprised to see that the plastic yellow anchors that connect with the body of the D3 are loose, maybe they relax over time. My noises now appear to be coming from the lower tailgate - potentially the swing up plastic / carpet plate. I'm going to remove the lower tail gate trim next. Then I'll remove the side pieces and re-evaluate. The interior noise has been so bad that I've contemplated seling my D3. Now, I look at it like a challenge. I'm going to find the culprit(s) and reply with what I find. Give me a few weeks.
