I only have 67,000 miles on the OD it is a 08, 2500 Mega Cab 4X4. I have had a 4X4 vehicle since 1974 and three of them have been Jeeps or the Ram truck. My other 4X4 vehicle’s where a Ford Explore 1992 that Turned Turtle, a Chevy pick-up truck and Chevy Blazer. My sons have all had 4X4’s either Jeeps, Fords, Chevy’s or Ram trucks.
This is the first time I ever had an issue with the front end other then shimmy to the front wheels do to worn out front steering stabilizers on the Jeeps, stock size tires and rims. The Jeeps were full size Cherokee’s with the solid axles similar to the Ram trucks. I use to take the front hubs apart and repack the wheel brg’s every 12,000 miles. So I know what a good and bearing that is starting to fail looks and sounds like.
I have checked the front u-joints for wear and looseness on both sides. They are tight but the needle brg's could just starting to go bad. This is why when the truck gets up on the lift I will be looking at the u-joints again before replacing the unit wheel brg’s. Usually the u-joints will squeak either under load or not under load when subject to movement such as the front wheels being turned. When I apply the throttle pedal to the engine to apply power to the drive train there is no noise emulating from the front wheels. When I go to turn there is a slight low squeak at or below 5 MPH not under load; faster than 5 MPH then there is no noise. So the truck is on limited disability and only used if the Jetta is not available until I can get it fix.

That sounds like a dry cross for sure.
Just for reference I replaced both front axle u-joints on the '06 at 67,000 miles. Now at 130,000 miles I can hear a snap when in 4WD on soft ground. Last time that I greased the truck it only seeped out of three of the four seals on the LH u-joint so I'm pretty sure I know where the snap is coming from... .
