Solution

1. Preparation

Gather tools and parts required for the repair.
Safely lift the vehicle using jack stands and ensure it is secure.
Disconnect the battery to prevent any electrical issues during the repair.

2. Remove Driveshaft

Sub-steps:
- Remove any protective covers or shields that may obstruct access to the driveshaft.
- Mark the position of the driveshaft for reinstallation alignment.
- Using a socket set, remove the bolts securing the driveshaft to the U-joints at both ends.
- Carefully slide the driveshaft out of the transmission and rear differential.

3. Replace U-joints

Sub-steps:
- Using a U-joint press, remove the old U-joint from the driveshaft.
- Clean the U-joint yoke surfaces where the new U-joint will be installed.
- Apply grease to the new U-joint and install it using the U-joint press, ensuring it is seated properly.
- Secure the U-joint with the retaining clips provided.

4. Reinstall Driveshaft

Sub-steps:
- Align the driveshaft with the marks made earlier to ensure proper positioning.
- Reattach the driveshaft to both the transmission and rear differential using the previously removed bolts.
- Torque the bolts to the manufacturer's specification (typically around 15-20 ft-lbs, but consult the service manual for exact values).

5. Final Checks

Sub-steps:
- Reconnect the battery and lower the vehicle.
- Start the engine and check for any unusual noises or vibrations during operation.
- Test drive the vehicle to ensure everything is functioning properly.
