Wind whistling sound and an intermittent serious squeal. How do I check the turbo?

Pull the intake from the turbo and check the compressor wheel out. You may have a boost leak.

Sounds like a boost leak, but Graves is right, check that turbo wheel. Should feel like almost no resistance to spinning with your finger.

More likly belts,,any power loss? Smoky exhaust?
Unless chipped or injector mods,, turbos can last,,unless leadfooting
Check all pulleys,,had a tensoner pulley do the same thing,,till saw it fly off ,bang the hood,and fly down the road.
Battery light came on immediatly,,amp gauge went 0 no charge.
But go to either Powerstroke.org or PowerstrokeNation.org

not a belt. No smoke but it smells like hot oil after a short run. Some power loss. It feels like the turbo bearings are going out if I had to guess but this is my first turbo issue. The squeal has a vibration with it that reminds me of pumps needing bushings

Turbos are feed oil to keep them cool and lubricated. This could be the early stages of oil starvation to the turbos for what ever reason. Or perhaps the turbo bearings are wearing causing the oil to get a bit hot. Hard to say at this point.
