Actually being armed markedly increases your likelyhood of being shot. Both by accident, on purpose as you present a threat, or with your own gun. Theres plenty of stats to show that. And ghosts and spirits dont exist. But ignoring all that, I have no idea! Howling?
If it was motor or gearbox related you would expect the frequency to change with speed. So no clue. If it was a really high frequency like a dog whistle then it can be the frequency of the Pulsewidth signal feeding the motor as this is constant frequency but its up at about 18K. So you woudnt likely hear it if above about 20 year old. Although my old dog could.
Is the tyre catching a plastic panel, which is vibrating at constant frequency, or a cable? Jack the wheels off he deck and run it and look carefully.
