can you be more specific? i have trunk problems too
Theres actually a combination of things that make noise back there.
First is the obvious plastic lid
Second is the rubber blocks mounted to the car that mesh with corrisponding plastic blocks on the hatch itself over time they get squashed and allow the hatch side to side movement (if you can find the hatch support shocks you can find these
Third is the rubber hatchseal which over time gets squashed and will squeek and easily fixed with some silicone spray or even armor all.
Add all these together and it sounds like the damn back of the car is falling off
