driveline noise - 2012 Ram 2500

[TnT_M]

I need some help folks. My 2012 Ram has a weird sound in the driveline. I was pretty sure it was the front driveshaft u-joint to the transfer case. I removed the front driveshaft, but the truck is still making noise. I certainly is a mystery to me. I'm now wondering if it is the carrier bearing in the rear driveshaft. Any advise or ideas would be great. The noise is coming from under the truck but is difficult to locate. It only happens above 20MPH so difficult to diagnose.

I chased driveline noise for 2 years and couldn’t find it until I ran the car in gear with the wheels all in the air and walked around. All this sound from the rear was being carried forward somehow through the chassis. Was plainly obvious outside.
