Problem with a happy (silly) ending
Last week I starting hearing a "clunk!" whenever I started from a standstill or came to a complete stop. I thought, "great, I've already shipped all my hydraulic jacks and ramps down to Florida... my OE car jack is the only lifting device I have left. Now I have this noise that sounds like it's coming from the rear-end or drivetrain." After 2 or 3 days of that I went on a deep search beneath the trunk's carpet to see what I had stashed down there and I noticed that in the main trunk area I still had a 2-plus foot-long super-heavy breaker-bar with a 17mm socket on the end (which fits the wheel-bolts).
Well, when the "clunk" sound began I had removed the Windstop inside its protective cover from the trunk... but it never dawned on me that it was keeping the breaker-bar from rolling all over the trunk! Sure enough, I removed the breaker-bar and the noise went away! 😏😁👍👏
