Re: Roof rack cross bar wind noise

How do you know if the bars are on backwards? I have the shorter end in the back.

Should look like an aeroplane wing (blunt in front, tapered in back).

Re: Roof rack cross bar wind noise

My father-in-law bought a 2013 Grand Cherokee Overland 3 weeks ago with a Mopar roof rack. He complained about wind noise and when I rode in the vehicle for the first time I couldn't believe how loud the noise was. Looking at this site, we determined that the noise was as much resonance as actual wind noise, and that the bars were possibly facing the wrong way despite what the factory sticker pointing "forward" indicated. We confirmed by looking at the Thule aerodynamic cross bars that, in fact, the thicker side of the bar should face forward as the leading edge with the thinner edge in the rear, exactly like an airplane wing. Ten minutes later we turned the bars around, headed out on the freeway, and noticed 100%+ improvement in the wind noise, to the point of almost being undetectable. Bottom line, the Mopar factory labeled the bars incorrectly, the Jeep dealership followed their lead, and the bars were installed incorrectly. Flip them around so the leading edge is thicker and you'll have almost no wind/resonance noise from your beloved Jeep and its roof rack.

Re: Roof rack cross bar wind noise

Thanks to all for all the information regarding the cross bars!
I just put mine on yesterday and have a really bad wind noise. Im looking forward to getting home after reading through everyones posts and switching them. One thing, some ppl mentioned that the front vs back sticker was switched also. Do you all know if the shorter rack goes in the front or back. Right now I have the shorter one on the back......

Re: Roof rack cross bar wind noise

Hello Jeep Garage! This is my first post. Just bought a 2014 Limited Maximum Steel. I also just put up the Mopar crossbars. I moved them 24" apart and I have them facing the right direction.

The Wind Noise is CRAZY... The rubber that fills the inner void is not sitting totally flush on top. It is seated correctly but with the pushing and prodding getting it in there its not completely flat. I read one user say that 3 days after installation the noise went away. I wonder if the rubber will heat up under the sun the next 72 hours and perhaps lay flat (If the rubber is in fact the culprit.)

I may have to ditch the racks and only use them when needed but I'd hate to do that.

I have mine moved as far apart as possible and I have no wind noise with the exception of going across one of our floating bridges when the wind is just right. Try adjusting the location of the front bar and see if that helps.

Re: Roof rack cross bar wind noise

Thanks DirtyDuc83, I have the front bar just about as close as I can. Perhaps ill try going further.

I did try a test last evening and used paper tape across the top to ensure the rubber was completely flat. I did this only on the front cross bar and only on the front part of the crossbar (1 strip of tape). After a test drive the noise was still there. So I taped down the the front and back of both cross bars (3 more strips of tape). This resulted in a dramatic wind noise reduction. I'm almost convinced that the rubber seal is the culprit in my case.

Re: Roof rack cross bar wind noise

ug, mine are making noise! I double checked and triple checked and I followed the stickers and the fat end is facing forward on both (the mopar sticker is toward the rear). Does the longer one go in the front or back? maybe thats the problem....

Re: Roof rack cross bar wind noise

After my paper tape test i was convinced it was the rubber seels that were not laying flat that were the cause of the noise. I slid them out of the rack and spent a little time bending them with my hands so that I was forming a "V" or "C" shape. I then slid them back in the rack.

Result = NO WIND NOISE (Or so minimal not worth removing them)

I've had racks on the last 4 SUV's I have owned. The noise now is comparable if not better than I have had.

Hope this tip helps others.
