"Clicking" front end sound

[GMC-AT]

Ok,,, I have been trying to narrow down what is causing this clicking sound...need some help. Here is what I know..

1. The clicking sound happens with the rotation of the tires. increases and slows down with speed.

2. Only happens below 15mph. But doesn't always happen. Sometimes it will be quiet for a few min.. then start again.

3. putting the truck in 4x4 doesn't change anything.

4. I put the truck in neutral and coasted a few times... no change...still clicks

5. I applied the breaks (to compress calipers) while keeping speed.. no change.

6. Sound happens when both driving straight or turning. Doesn't matter.

7. Checked lug nuts.. all tight

 

Any ideas?

I'm gonna say that T30 torx bolt that secures the rotor on the hub came out in between the rotor surface and the rim and it's flopping around on the backside of the rim. Take the front wheels off. See if they are still tight and in place.
