Default Why is my C7 so damn creaky?

I did the fix roof trick with the grease and spray. I guess it worked a little but I still hear pops and creaks. I'm thinking its the warm weather things expanding and in cold they contract. Is this just part of the game or should I take it to Chevy and see what they say. Its rather annoying when you take someone for a ride in your new sports car and they say what is that noise!!!???

Also does anyone know how many foot pounds the locator pins should be torqued to. It was 16lbs on the C6 I'm not sure if it's the same for th C7. I havent tried that yet.

I have the same problem on the driver's side of the roof. I also did the roof fix with very little results. I seem to hear the creaky noise when I first get in the car and drive over uneven pavement. Should I take it to the dealer.

Right same here except mine seems to be mostly on passenger side. I think there are two things on the roof that need to be torqued to a certain pressure. Maybe ours isn't. I will look in manual tomorrow to find out exactly what two things and what ft # they need to be.

My creak is on the driver side. I have tried silicone grease and spray. It does have something due to warm weather. Mine is a painted roof. 2015.

I read on another forum someone took their car for the same issue and the service department told him its normal and it's because it's a new car. If it's still doing it after 7k miles then bring it back. Lmao I hope that's not true.

I had bad creaking from the driver side. I put dielectric grease on the pegs and in the holes the pins sit in. I then used a pure silicon lubricant spayed on a micro fiber towel and wiped on the seals.

Since doing this about a month ago, I have had no more creaks. I took the top off twice and still no creaks.

I think other's issues are worse than mine but it did drive my nuts until I.did this. Below is the stuff I used.

No, I did not need to tighten anything.

I'm not suggesting what worked for me will fix everyone's issue. Mine could come back for all I know. I have put about 1000 miles on since applying the grease and silicon. Took it out today with top on and was fine. No creaks.

Mine creaks a little when cold and buzzes like hell on some roads...all kind of temperature sensitive rackets and noises...same as all my c6's...Some things aren't better with the Stingray...sadly.

It is still a Chevy after all.

Mine is a year old and I hear some minor creeks when backing out of the driveway. I just started hearing it about a month ago, I was wondering if it had anything to do with the temperature change? It's not something that I would take it in for unless it got worse.

There is another thread on the forum addressing this same issue where it sounded like the main fix was to put small O rings on the front posts. I guess the extra pressure holds it all together tighter when the roof is on. Wonder why nobody has mentioned this earlier in this discussion?

I'm even a bit leery of even taking off the roof with all the comments of creeks and squeaks I have read about after you do. Anybody remove the roof without problems later?

After almost a year of ownership I'm definitely hearing more wind noise :-\

Mine does it a little over very rough roads. I don't think it did until I took off the roof. Car has 3k miles on it.
