  1. So it started raining inside the truck on Sunday. 2015 Silverado. I removed the shark fin antenna. Cleaned up the sealing surfaces and applied pure silicone sealant. We'll see how long this works. A hole in the roof is not a very bright idea.
  2. I gave it a try today. I drove at 65 to 70 miles per hour. windows down and under 7 overpasses. I did not hear any whistling. I 2015 2500HD LTZ passed me doing a few miles per hour more than me. I did not hear any whistle coming from the LTZ as it passed me. The whistle must not be something that happens will all of the 2015 HD's.
  3. I'll give it a try next week. I'll let you know if I hear the whistle.
  4. I have a 2015 2500 6.0 Chevy 4X4 crew cab with the old style black tow mirrors, XM antenna, no moon roof, no roof lights and no noise. Build date was in July 2014. This is the quietest truck I have ever owned. Or maybe my hearing is getting very bad. I hope you guys are able to figure this out.
