“Clicking noise” while in 4WD and while under torque

My avalanche has recently started making a ticking noise when in 4WD and while the truck is under torque. And example of “under torque” is trying to get up and over a rock or going up a steep hill. I believe this issue is also causing me to loose torque. I suspect this could be slipping in my front diff or perhaps a u-joint or CV joint on my transfer case to differential drive shaft. I will try to attach a video of the sound. If you have ANY information it would be greatly appreciated.

 
I would jack it up and start checking front end and axle parts.
