Vibration issue

[TOM R]

I run royal purple in the center diffs and the planetary hubs ,no leaks, I also have a lift so I've been under the truck and checked everything I could think of with a prybar

Thank you all for the comments. Turns out it was the water pump. Bearing was out and coincidentally developed a small leak around the oil fill tube mixed with the leaking coolant looking like an oil leak. Repaired, no issues and runs cooler now.
