Strange clicking/tapping sound coming from under driver side

There is a strange clicking tapping sound coming from somewhere under my side outside the truck. Only hear it when the truck is moving and gets slightly louder when I make a left turn.

I checked all the steer and drive tires to check for any impaled stuck objects. Checked under the truck for dangling loose hoses, wires, belts etc... did air brake test. Checked springs, bolts, etc...tried everything to the best of my knowledge.

Truck runs fine though on the interstate...no shaking or rough handling.

Let me know if you guys have an idea what the problem might be. thanks

 

This is a 2016 Volvo vnl 670 Detroit engine. Only hear it with the window down. Seems like it makes a clicking sound with every tire rotation.

 

Maybe a wheel bearing? I'm not too sure. But hoping I can learn from this.

 

Still hear the sound when brakes are applied down the road. I have checked all tires pretty good. Going try and find a way to get under the truck to take a harder look.
