The Michigan weather has turned a little cooler and I've notice this noise. Did a search and summarized my findings below. I was just wondering if anyone tried any other solutions.

When the top is down, some owners hear a faint annoying clicking noise from the folded top frame just to left of their head while driving. Colder weather seems to make this condition more noticeable. One owner reports the solution is applying a small amount of Teflon lubricant to all joints. To apply he lowered the roof half way and stuffed paper towel behind the joints to catch the over spray, wiping off the excess when done. It takes a couple days for the lubricant to work in and smell to go away.

 

check the library there might be a TSB on the roof clicking

 

Like I said originally, "Did a search . . ."

This is a different problem than the TSB to replace the noisy latches when the tops up. This has to do when it's down.
