I'll try and make this simple. The crossbar that goes over the top of the cab makes a whistling sound when you hit about 45 mph. I figured it would because it had happened to me years ago using a round bar. On my last truck I had the bar out in front of the cab. Now that I have a 4 door though I don't want to extend the rack out that far. There are 2 bars over the cab and the front one is a little higher off the cab than the 2nd one. I have the rack down at the powdercoaters now, but would go down there and cut off the 2nd bar if I knew it would stop the noise. Also the top part of the rack is only bolted on to the bottom part so most of the time I will not even have the extension on. Does anyone have any info on this and how far the bar would need to be above the cab to stop the noise. Thanks to any advise. Scott
