My hatch in my 97 LS rattles a LOT. It does it when I'm driving down the road, and it makes a lot of noise at even the slightest bump or or dip. I can't really tell if its just the black plastic on the hatch itself thats making the noise, or if the acutal door is rattling loose. Anyone think of what my problem might be and how to go about fixing it? Appreciate your help!
