There are a few possibilities to look at.
First, the brakes could be rubbing against the heat shield or the caliper pins could be binding. When cornering forces are put on brakes they do **** sideways ever so lightly. It is the first thing to look at because of safety.
Next I would consider the constant velocity joints in the front axles.
Also, the suspension could be worn, i.E. Tie rods lower ball joints are generally the first items to fail on high mileage trucks. They can cause the axles to bind and make noise and it can cause the brakes to **** more.
The brakes are somewhat unlikely as the movement is very minimal. However, trucks have more issues like this as the forces seen by components when cornering are large due to the weight of the truck.
A few questions;
Is the vehicle 4-wheel drive?
If so, does the noise differ when in 4-wheel lock?
Are the brake rotors ridged at all? Or anything othere than a smooth surface?
If you have a jack, lift the front end and put jack stands under the frame. Then grab the front rims at the top and bottom and see if there is any, "play".
Let me know what you find and I will keep an eye on this post and get back ASAP.
