First look for any u-joints in the steering shaft going down to the gearbox. They can bind and will sometimes have telltale signs of reddish rust around the bearing cups. Next, put your hand on the steering linkage in different places while a helper turns the wheel. See if you can feel that pop. As a last resort, disconnect an inner or outer tie rod end from one side then the other to see if the noise is gone when turning just one wheel. That will isolate it to one side. A ball joint can bind when it's supporting the truck's weight but turn freely when inspecting it jacked up.
