Solution

1. Preparation

Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Gather tools and safety equipment before beginning the repair.

2. Raise the Vehicle

Use a hydraulic jack to lift the rear of the vehicle.
Place jack stands securely under the frame to prevent the vehicle from falling.
Safety Warning: Ensure the vehicle is stable before working underneath.

3. Remove Driveshaft

Use a socket set to remove the bolts securing the driveshaft to the differential and the transmission.
Carefully slide the driveshaft out of position and set it aside.

Take the U-joint to a workbench for easier access.
Use a U-joint removal tool to press out the old U-joint from the yoke.
Clean the yoke and apply grease to the new U-joint.
Press the new U-joint into position, ensuring it fits snugly.

5. Reinstall Driveshaft

Align the driveshaft's splines with the transmission and differential.
Reinstall the bolts, tightening them to the manufacturer's specified torque settings (typically 15-20 ft-lbs, but verify with the service manual).
Double-check that all connections are secure.

6. Lower Vehicle and Test Drive

Carefully lower the vehicle back to the ground.
Start the engine and perform a test drive to ensure the issue is resolved.
