Has anyone experienced wind noise on an 'original equipment' cross bars. At highway speedsI get this whistling sound. It was fine with just the roof rack rails.

 

I don't have the Oem one but I have Thule and I have to use the Thule fairing so I don't get the noise. Don't know if Mitsu makes one for there Oem crossbar.

 

I have Thule with no fairing. I dont get a whistle or any noise thats too loud.

 

I have Rola crossbars and they make noise above 70 km/h (aprox 45 mph I believe). Easy enough to remove if they get too annoying. I have to take pictures before I remove them.

 

What is the model of your crossbar do you have the Aero one?? I have the LB50 the black square one and without the fairing there Buzzing over 70km/h.

 

I just install a brand new pair of Thule last week. I experience the whistling sound even @ 30 miles/hour speed. I am wondering if intalling the wind deflector on the sun roof can help, since I don't like the look of the fairing. If not, I will return the cross bars. Any suggestions?

 

After I got the fairing on the noise was gone and it's my 3 car with Thule rack I install the fairing on all of them. At first I did not like the look but I really do now give a sportier look to it.

 

I had a similar problem with Yakima cross bars. Though it was more of a low howl than a whistle. Bought the fairing on roach's recomendation and the problem went away.
What I am concerned about is what happens when you are using a ski box and the installation does not allow for the use of the fairing? Does anyone have crossbars with the sunroof wind deflector?

 

I have the Thule Bars with a Thule Atlantis 1200Box, I noticed a bit of a sound when I installed it, but I was surprise at how little noise it made, I don't have the wind deflector, and the level of noise I'm getting is not going to make me get one. One thing that might make a difference is the possition of the bars, my front one was about 5 inches from the front of the rails, and the rear one was about 6 inches from the back.

 

I have a thule with the lb50 bars and a bike rack and an Evolution 1600 box....the noise is really not that bad...and if I close the sunroof (cloth) panel I do not hear anything (there is not use for the sunroof anyway with the box on top).
