Learn more about the installation of your truck rack
Anytime you install any aftermarket product on the exterior of your vehicle you are changing the aerodynamic flow of air around the design of your vehicle. This is not limited to just the installation of racks but any product like window visors, roll bars, brush guards, etc. Here are some helpful tips on what to do if you experience any excessive wind noise or whistle after installing truck or van racks.

Experiencing noise, such as whistling from your rack?
- Reread through the installation instructions enclosed in your parts bag.
- Be sure to check to make sure all hardware is fastened securely.
- Periodically check to make sure all hardware is securely fastened and the rack is in good repair.
After you have properly installed the rack and all the mounting hardware is tight, be sure to seal all areas where tubes telescope. This will not only prolong the life of your rack by disallowing moisture to enter inside the cross bars (especially on steel models), it will also block wind, reducing whistling and keeping everything tight and secure.
Nine times out of ten, simply moving the front crossbar forward or backward a few inches will dramatically affect any noise. If the front crossbar is in direct flow of air coming off the windshield, move the front bar out of "the line of fire".
