Solution

1. Preparation

Tools Required: Jack and jack stands, wheel chocks, socket set, torque wrench, grease gun, U-joint removal tool (if needed).
Ensure the vehicle is on a flat surface and secure it with wheel chocks.
Raise the rear of the vehicle using a jack and secure it with jack stands.

2. Remove the Driveshaft

Sub-steps:
1. Disconnect the negative battery terminal to prevent electrical issues.
2. Remove the rear wheels if necessary for better access.
3. Unbolt the driveshaft from the rear differential using the appropriate socket size.
4. Unbolt the front of the driveshaft from the transmission.
5. Carefully slide the driveshaft out of the vehicle.

3. Inspect and Replace U-joints

Sub-steps:
1. Visually inspect the U-joints for wear, rust, or play.
2. If replacements are needed, use a U-joint removal tool to press out the old U-joints.
3. Clean the U-joint yokes and apply grease to the new U-joints.
4. Press the new U-joints into place securely.
5. Ensure that the U-joints are properly aligned in their yokes.

4. Reinstall the Driveshaft

Sub-steps:
1. Position the driveshaft back into place, ensuring it aligns correctly with the transmission and differential.
2. Bolt the driveshaft back to the rear differential and the transmission using the specified torque values (usually around 30-50 lb-ft, refer to specific service manual).
3. Reattach the rear wheels if they were removed.

5. Final Checks

Sub-steps:
1. Reconnect the negative battery terminal.
2. Lower the vehicle from the jack stands.
3. Perform a final inspection for any loose bolts or components.
