So for Thanksgiving I drove from Nashville, TN. to Green Bay, WI. (678 miles one way). I used Thule Square bars and the Evolution 1600 box. It sounded like a jet airplane was on the roof the entire trip. It was placed all the way to the rear of the vehicle to where the hatch hit it. It sounded like most of the noise was coming from the bars. Any secrets please let me know. Thanks


Question one: Has anyone else had this problem?

Question two. Has anyone try moving the box forward in attempt to have less noise?

I just did 10 hours (each way) in our XC90 with the Thule 2100. The sound is noticeable, but not horrific. If we have the sunroof shade closed, and radio on, its hardly noticeable.

I usually position it so that there are only a couple of inches between the back of the box and the position of the rear lift gate in raised position. My 2100 is probably bigger, but I would guess the front extends about where the 1600 does on your XC60. Just slide it forward to try. However, not sure any of the positions will make much of a change.

I haven't put the roof box on my new XC60 yet (need to buy a new foot kit for my rack), but I've been using Thule racks on my cars for the last 15 years or so. There is really no way around the noise. I generally keep my roof rack on my car full time. There is always extra noise and a bit of a mpg hit (particularly on the freeway). But I use the rack often enough that I rarely remove it.

I'll tell you what I do to deal with the noise. I go for a drive on the highway in my Jeep Wrangler. After a few minutes driving an aerodynamic cinder block on wheels at 75mph with no headliner or roof insulation, anything seems quiet by comparison. This may not work for everyone, of course. ;)

I would not recommend the Thule wind fairing. The one in the link above is newer than the one that I have, but my problem was that while they do cut down on the noise, they also trap dust & dirt where they contact the car. This eventually wore a scratch across the roof of my car. That may be acceptable on an old VW, but I wouldn't risk it on my XC60.

I switched my Thule square bars to the new Thule Aeroblades. I have also switched from the Thule Atlantis 1600 to the Thule Atlantis 1800. The longer 1800 seems to fit on the vehicle great. It does hang over the front a little. I am hoping that the longer box has a little less noise. I am planning on taking the mounts off the box and using the Xadapter 10 to mount the box flush with the Aeroblade cross bars. Will keep everyone updated on the changes.

Roof box noise improvement

So for Thanksgiving I drove from Nashville, TN. to Green Bay, WI. (678 miles one way). I used Thule Square bars and the Evolution 1600 box.

I have a Thule ski box that I bought for my old 98 V70R that uses the rectangular crossbars. Since it wouldn't work with the new oval crossbars, and I certainly didn't want to buy a new box, I kept the rectangular ones, and it was a bit noisy. I had a Thule air deflector for the old setup (designed for the bike rack actually) so I monkeyed around and installed it on the XC60, and it is *much* quieter. There is a foam edge on the air deflector that touches the roof - not sure if it will leave a mark, but it should polish out in the spring.
