I have had a rattle coming from the rear drivers side and just checked the nut that comes into the interior where the speakers are. Sure enough the left rear nut (17mm) was loose. The right side was tight. I turned it but it did not tighten. Just spinning the whole thing. I assume I have to hold something under the car to get it to tighten. Anybody had to do this? When I first had my Koni and lowering springs put on I had to take it back and they tightened it but not sure how exactly how he did it. That was years ago. I was ready to order new rear upper mounts. Maybe I don't have to. I want to get this tight and check the noise again. Any advice on this appreciated. Thanks.
