Try the cheap and easy solution first. With the Yakima crossbars mounted on my Subaru, I found that the noise level was noticeably reduced by adding a length of foam pipe insulation to the front crossbar.I just installed a Thule Crossroads rack. Impressed by the quality of the unit but WOW it’s noisy above about 50MPH. Curious if anyone has tips for reducing wind noise (location, fairing, wrapping bars, etc). Thanks!
I put 4 cross bars up top in order to mount some textilene shades for the summer camping, (heats up slower under the sun, helps sleep in along with insulation and ventilation) and the frontmost bar was right above driver’s head and was makin wind noise.it was a problem not just for noise, but it meant the wind would hit the textilene shades as well.
I attached two layers of (search:universal lip spoiler, trunk spoiler) tape-on spoilers and the windnoise is gone. The spoilers probably make nouse as well but it is very subtle as I can’t really tell. Sends the wind over the first bar, and textilene stays put up to 80mph - didn’t text any faster.
Give it a try, oh, and the lower lip spoiler right above the windshield, I ground out 3 small channels on the bottom side of the spoiler to let rain water drain out when parked, as it is curved in a U shape and would make a luttle pool otherwise.
