Thanks for your replies so far.
Father in law was in town over the weekend and we inspected the truck:

From what I can hear it, it sounds like its coming from the left rear tire. So I dont think its anything up in the front end. We did inspect the front area but didnt see anything out of the ordinary. But you are right on the sound. Its a clicking noise and its an even click when it does it. It doesn’t speed up or down with the speed of the truck.

Maybe it's a loose pad or sticky caliper?
I hear the sound as I apply the brakes through and turn the wheel during a turn. Sometimes I will hear it if I am just coming to a stop, however it happens more often when I slow for a turn (not actually come to a stop), turn, and accelerate off the turn. Seems like it likes to do it more on right hand turns than left, but I have heard the clicking sound on both turns.
Other than that I dont hear it backing up and turning or any other times. The truck seems to drive nice and I dont notice any problems in acceleration.
From where I thought he sound was coming from (left rear) we pulled the tire and caliper and really didnt see anything wrong. Brake pads looked good, caliper and bushings moved with no resistance. The father in law did make notice that when the caliper was mounted back to the hub/wheel assembly that it did have a play to it. It wasn’t stiff. You could move it with your hand like an eight of an inch side to side. He said he never seen a brake caliper with that much play in it. Not sure if that has anything to do with it.

Ujoints looked tight. Normal wear and tear on them. Havent thought about replacing them but it looks like it could be a cheap fix that could possibly fix the problem.
Now on a whim my father in law wanted to check the fluid level in the rear differential. He pulled the fill plug off and stuck his pinkie in and it was covered, as well as the end of the fill plug, a sliver like grease. Almost look like that anti seize stuff. He check the level with his finger again and said he could not feel any fluid in there. He said it should be pretty much level with the fill plug. We went and bought a quart and poured about half in. It didnt really seem to help the click issue much.
From reading my owners manual it says that I should not have to change or add any fluids to the rear differential. So I am not sure if the fluid level being down might have caused something to break and thats why I am hearing this clicking noise?
