So I have this wind roar at about 70mph and up. I'm going to take a long ride south in a few weeks and want to make sure it isn't too annoying. So I know all about the gap bit between the waterfall and the trunk. I wasn't sure if that was it so I taped the gap and the noise is still there. I have another theory. Underneath the cover, the part that makes contact with the black strip on the waterfall, there's a rubber seal. If you lift the seal you'll see the aluminum frame of the cover. I noticed that on both curved edges, the corners of the cover, there's a thick black rubber piece. This seems to push the seal out and doesn't allow the rest of the seal to make good contact. I don't know if they're supposed to be there or if they can even be removed. Can someone else check to see if their car has them? I guess I'm just wondering if they weren't removed from the factory, but I don't want to pull them out if they're needed.
Thanks!

You lost me a little...can you post a picture and I'll take a look.

My black rubber seal is flat all the way around. It should not be sticking up higher than the waterfall anywhere. If it is, then the top can not lay flat.

What kind of exhaust is on the car?

Keep the top down the entire way problem solved

Might check this out as well.

Hopefully this pic helps out. The rubber piece I'm referring to is the one right between my fingers.

masihman

anyone able to check this out for me?

Ketchum

You sure its not exhaust drone?

masihman

definitely not exhaust drone. it's the stock NPP.

My vert (2005) does not have the block of rubber showing past the rubber seal like in your picture. In fact mine does not have the rubber block at all and I suspect you are on the right track.....Could it be a shipping block that was not removed?

Here is a pic of mine.


Here is underneath the seal...no block present


Here is a pic of the same area when the top is sealed to the tonneau cover...shows a flat seal.



Hope this helps!

Mine has the same black blocks (it's under the rubber seal), and appears to be plastic. Seems it is a protective backer for the bolt right there.

Close your top and see if there are any gaps along the bottom, try to slide a piece of paper under it. Could be a bad rubber gasket or the pneumatics could be off ...

Wind noises can be tricky to find.

I think best bet is as above....take same paper and test the sealing tension of all the weatherstrips.

(Seems some have these blocks you photo'd).

JKbride

Yes, it seems to me the frames are different widths. The 05 frame seems to be squarer and thicker vs yours seems to be more rounded and thinner.

In 05 there was a big delay in getting the top to work right and I suspect GM made some changes in later models to improve its performance (although I have not had problems) so it does not surprise me the tops may have some differences.

You can take some chalk and put it on your seal and it will lay an outline where it is setting on the car. This will help you trouble shoot the precise location if you have a break in the seal.

Ketchum

Masking tape. Tape various areas and test drive. Narrow it down.

My 2009 has that piece but it doesn't seem to deform the rubber seal. I don't notice any wind noise any more than I'd expect from a vert.

You might also want to check to see if your windows are sealing properly. There is an adjustment to make the wingers press against the surrounding seal. I have had it done at a trim a trim shop, did not attempt myself.

JKbride

Another good area to check....

masihman

Can you explain what you mean by wingers? What are wingers?

It sounds as though there's very rough turbulance above the top and the whole thing sort of shakes. I don't remember this at all in my 05 vert. I also was wondering if it's possible that the Z06 style spoiler on the back could be the cause since it's steeper?

masihman

Damned, I was hoping that was the cause. I have noticed that these rubber blocks have caused the seal on the waterfall to be slightly indented where it is, meaning it's putting a lot of pressure on it. I'll try the paper test and see what happens. Thanks for taking a look and the pics guys!
