Im hoping it subsides when I install by traction boards but im not holdng my breath. Anyone have sucess suppressing wind noise on these type cross bars?

I've seen people wrap bungee cords around them to break up the air flow. Just wrap one cord in a spiral down the length of each bar. Another option would be a wind fairing to direct the air over the bars.

Had very similar rack on a work van. Fix will depend on the type of noise.

1) wind whooshing pitch increases with speed try:
- adding a low angle wind fairing
- rope or bungie around cross bars. Vary number of wraps see what works best
- lower cross bars closer to roof if possible

2) hollow warbling sound like blowing over a beer\soda bottle... tape over any holes. Like the ones on the towers.

3) vibration
- tighten everything re check after 50 then 150 miles
- lower bars closer to roof if possible
- add weight to dampen

Look at a Thule rack and copy what they do. The one thing that will help most for the noise is a plastic wind deflector onthe front of the rack. For a quick cheap fix to see if you can kill the noise would be go to Walmart and get a pool noodle cut a slit lengthwise and zip tie it to the front bar it should deflect most of the wind.

I wrapped a Poly rope around mine. Helped a lot.

I dont know how married you are to that rack in particular but I few things come to mind:

1) are you sure it's not the shovel causing all that noise?
2) any holes will make noise
3) try the much- mentioned wind fairing
4) Trac Rac (now owned by Thule). They do pickup racks, van racks, and racks for pickups that have a Leer (or similar) bed cap on them. Very strong and very quiet

Thanks to everyone for the suggestions. Wrapping the bars with bungie cords did the trick and its now nice and quiet!
