when i'm driving down the road i've begun to notice a slight clunk in the rear end... i'e pretty much isolated it to being the trunk lid (the hatchback) as a result of a little play in the latch. is there a way to tighten the latch mechanism to get it to stop doing this? also, i've only noticed it recently... i only bought the car last week and it wasn't doing this at all, however, its also about 40 degrees colder out now than it was last week, is there any rubber in there (isolators) that may have simply shrunk with the temperature change?
