    I have a standard "Campmobile" front rack. But I find the wind whistle starts just above 60kph.

    It doesn't seem to be a problem when I use a roof bag full of stuff.

    Has anybody else come up with any solution to reduce noise?

    And yes Col, I have thought of "remove it"!

    How about a "fully sic" front spoiler wing to deflect the air away, and increase downforce??????:rolleyes:

    Check out the "ricer burner" forums, for shape ideas.:D

    Have seen some people wrap rope around horizontal cross bars.
    Claims that this shuts it up.
    So its either dampening the vibrations or disturbing airflow .
    My guess is change tuned length of bar by dampening or stiffen at centre / change airflow n see what happens.

    Try moving it a few cm.

    Yep, I am one of the rope wrappers. It worked magically. Plus you get to have a spare rope on hand just in case it is needed.
    My rack vibrated on the freeway and it turned into quite a loud hum. Rope stopped all of the noise totally (apart from every other area of the bus that makes noise.

    Thanks for the various suggestions. After a bit of googling I found many suggestions of the rope or strap, adding some padding or moving the rack. There seemed to be no real acceptance of those wind deflectors.

    Trouble with a camper rack is - it cannot be moved really, and there are several cross bars. But I will try a few suggestions and see what happens.

    I've fitted a length of pvc pipe with screw on end caps to the front of the rack.
    Works really well & provides great storage for tent poles, fishing rods etc.
    Everything sits inside the rack.
    I'll see if I can dig up a pic.
    Cheers,
    Mark

    Hi Folks,
    I found that it was a 'tuning' problem also & used an ocker strap interleaved & wrapped around on the horizontals forward & back, in the middle, made a great difference. Cheap too! Must be that square bar not being able to fly & the way the air thus flows!
    Cheers,
    David H

    Just turn up the volume on the sound system to drown out those noises, and then enjoy the tunes! ;)

    That's exactly what I'm saying...
    ( the pipe AND the beer helps reduce the noise !)
    Cheers,

    You'll also find small holes in the underside of the rack sections. I used small rubber pull-through grommets from Clark rubber to fill em in.
