Solution

1. Preparation

Gather all tools and parts before beginning the repair.
Ensure the vehicle is parked on a flat surface, and set the parking brake.
Disconnect the battery to prevent any electrical issues.

2. Lift the Vehicle

Use a jack to lift the vehicle and place it securely on jack stands.
Ensure the vehicle is stable and cannot roll.

3. Remove the Driveshaft

Use a socket set to remove the bolts securing the driveshaft to the rear differential and transmission.
Carefully slide the driveshaft out of the U-joint, taking note of the orientation for reinstallation.

4. Inspect and Replace U-joints

Visually inspect the U-joints for any signs of wear, rust, or damage.
If replacement is necessary, use a U-joint removal tool to press out the old U-joint from the driveshaft.
Install the new U-joint by pressing it into place, ensuring it is fully seated.

5. Reinstall Driveshaft

Align the driveshaft in the same orientation as noted during removal.
Secure it with the bolts, tightening them to the manufacturer's specified torque setting.

6. Final Checks

Reconnect the battery and start the vehicle.
Lower the vehicle from the jack stands and perform a test drive to ensure proper operation.
