Re: terrible wind noise from RRO roof rack/cross bar kit

zOlt3c, first off, your have a great looking Jeep. 2nd, don't be bummed on your rack, I bet you will be able to sell it and not get a "bath" for them. Keep your chin up! I have used my mopar bars for a couple of kayaks (topside down) and with the right tie downs, it worked perfectly. Although, I haven't done a canoe and the kayaks may be different, I was very satisfied with leaving the racks up since I got them. just my two copper.

Re: terrible wind noise from RRO roof rack/cross bar kit

I understand your frustration, but why not take lemons and make lemonade? You're already knee deep in this. Instead of throwing in the towel and complaining about the terrible wind noise, why not try and fashion a fairing to see if that help with the noise at all? Go to the hardware store, buy a piece of plexi and try craft your own fairing?

IDK, maybe it's how all the time I spend hanging on the JK boards and seeing the stuff we deal with regarding poor fit and finish or the creative ways we have to make things work at times. It's part of modding a vehicle, you deal with it, you adapt and you move on to the next thing. I understand your frustration with the powder coating, but it is not an impervious finish. If you drag things along it, it will mar or scratch the finish. I'm sure there more too it as I've read of the complaints on his powder coating. I've spent $2200 on front/rear bumpers and rock sliders only to learn after the fact that the of the shitty powder coating the company uses.

Good luck with what ever you decide to do.

Re: terrible wind noise from RRO roof rack/cross bar kit

Moving the forward crossbrace back behind the forward vertical pier was a good move. Wind coming up over the windshield was probably coming into direct contact with it. You also had the crossbrace in a cantilevered position which might have created some harmonics, i.e noise. Some of it through the roof structure.

Re: terrible wind noise from RRO roof rack/cross bar kit

If RRO offered a fairing I'd be all over that. But making my own usually leads to a less then finished look. Additionally, I am worried about the fairing going through a car wash and getting ripped off or damaged. I just don't want to drop another $75 into this setup hoping it might marginally improve. Maybe I can find a Yakima fairing to borrow. I've also concluded that part of the problem is the crazy raked stance the Jeep uses, I am thinking that the RRO leveling kit, which lifts up the front end, may remove some of the rack from the slipstream.

BTW-- Noticing about 1 MPG worse with the rack in place.

Re: terrible wind noise from RRO roof rack/cross bar kit

The mileage drop is a given wen you start adding things case more wind drag. I understand what you're talking about. You're never going to learn to do something unless you try and succeed or try and fail. If you try something and it doesn't turn out exactly as you hoped, try it again and gain until you get the desired result. I took that approach when I installed my first audio system in a grand prix I once owned. kept refining the install 'til I was happy with it. I eventually one a show for amateur class.

If you're unsure if a fairing may work at all, a really cheap DIY you can try before taking the plunge with making or buying a fairing. Pick up a small sheet (4x2) of 1/8 or 1/4 inch press board (that stuff that's like heavy duty card board). Cut it out in the shape of the fairing you're looking for and install with cable ties and go for a test drive to see if there is in improvement. If that works, finalize your design and try your hand fashioning one out of plexiglas or work with a local glass shop to have them cut it to form.

As for a leveling kit, I'd advise against it as it will make your mileage worse. You'll be changing the aerodynamic characteristics of the Jeep by raising the front and creating more drag while also letting more air flow under the vehicle also causing more drag.

Good luck and hope you try it out.

Re: terrible wind noise from RRO roof rack/cross bar kit

I broke down and ordered a Yakima 44" fairing a few days ago, it showed up today. I went and test fit the fairing and it's about 1"-2" too long to fit between the crossbars. The bad news, I believe I will need to move the front crossbar all the way forward again. The good news, it looks like the fairing is just the right length to cover the crossbar and side rails when installed.

I also discovered that my passenger side door is not properly aligned with the body of the vehicle. This is definitely contributing to the wind noise. Hoping this is a simple adjustment in the door hinges, will let the dealer take care of it at the next service.

Re: terrible wind noise from RRO roof rack/cross bar kit

Got the fairing on earlier today, got the vehicle up to about 50 and so far so good, pretty big improvement in wind noise. I'm not thrilled with the way the fairing fits (or looks) -- The bars on the RRO kit must be thicker then the Yakima bars as the clamps won't close using the stock hardware. I had to substitute zip ties for the carriage bolts. I am concerned that it might take off at highway speeds but only one way to find out.
