Detailed Under-Truck Examination

What happens here

Underneath the truck, the owner points out the driveshaft and its various universal (U-joints) or constant velocity (CV) joints. He manually attempts to shake the driveshaft at the suspected rubber bushing area, noting a slight movement and sound. He also checks the other U-joints, which appear to be tight, leading him to believe the rubber bushing is the most likely culprit. He then notices an unrelated issue with a loose exhaust pipe, which he plans to address later.

Goal: Confirm potential driveshaft issues and observe other components.
