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.
