WHAT'S WRONG WITH MY CUMMINS??? CALLING ALL MECHANICS!!!

What happens here

This project focuses on diagnosing a persistent vibration issue in a 2000 Dodge Ram 2500 5.9L 24-valve Cummins Diesel truck. The owner suspects a driveshaft problem, possibly related to a rubber bushing or U-joints. The process involves an initial visual inspection under the truck, rigging a GoPro camera to record the driveshaft and other drivetrain components during a test drive, and analyzing the footage to pinpoint the source of the vibration.
