it's bugging the crap out of me! I've tried tightening the visible bolts and scews, no help. Is there anything anyone has done to cure this. Mine vibrates mostly when the sunroof is closed when at idle. I've read a couple posts about this but no solutions. people were saying the rails get worn out or something. is this correct? is the only fix to replace b/c if so, i'll live with it?
please help thanks

 

I assume that it is a sunroof on a CRX, With that said. When I used to have my CRX Si and the sunroof started to rattle it ended up being the threads stripping from pulling out of the track mount (The ones that the 2 allen bolts screw into for the sunroof cover). The only way I was able to fix the rattling was to fix the stripped threads by using helicoils to replace the threads. This may not be your problem at all, But it is a good educated guess from my experience with this problem. After the helicoils were put in I feel that it was stronger then it was from the factory IMO. Hope this helps you!

 

You can always buy one of these.
