Thought I'd share this with y'all....For the past year or so every time I'd shut one of the rear doors or slammed the trunk closed, there would be a 2-3 second rattling sound coming from the rear of the car. At first I thought it was the license plate just loose…wasn’t that…then I thought perhaps an exhaust pipe clamp come undone or other such undercar issue…wasn’t that either. For haha’s I sprayed some WD40 onto the trunk’s tension bar hinges/joints and goodbye rattle!
