I made my rack out of 1-1/4in square tubing for my truck this time and now I'm getting wind resonance. I made them out of round tubing on my other trucks I've owned with no problems.
I was thinking of wrapping the overhead cross members with thin ribbed vinyl tubing such as they use in swimming pool drain pipe, or filling the cavity with aerofoam spray can insulation, but not sure if it is dense enough to prevent resonance. Using mortar cement sand would be messy and impractical but that would work.
Next rack I'm making, I'm going back to round tubing.
Any help would be appreciated.
Thanks
