Driving the vehicle down the road way and it starts making a popping noise. No rhyme or reason. Sometimes going 35 some times 70. Sometimes straight. Some times around a curve. Sound like you ran over something and its hitting under the truck. At times just a pop or two at times multiple pops.

Yep this trucks had a problem with the front bearing hubs. It would be good if you can upload a short video of the noise and tell us where it is coming from, here is a video to show you how to change them out. I would do both fronts, can I ask if the truck has large tires on it? If so this makes the bearing hubs go out faster FYI
