Wind Noise Source

[kwayne]

I have an 08 Job 1 truck Spartanized for over 15,000 miles. From the day it was new I have noticed a weird noise that only happens when I am running 75+. It will vary in pitch, duration, and does not repeat every time you run the MPH up. It does happen more when you are running into a strong head wind. I have had it up to 125+ with no noise. I do not see any issues on the Dashdag and do not notice any difference in performance. This will happen during acceleration or at a steady speed. Does anybody have any ideas.

So, where do you hear this noise? I get a wind noise sometimes from my drivers side back door/window that aggravates the chit outa me. I get different noises sometimes depending on which way the wind is blowing. This is a big boxy truck cutting through the air.

The noise sounds like it is coming from the left side of the engine compartment.
