Sub-steps:
1. Mark the position of the driveshaft on the differential and transmission for reinstallation alignment.
2. Using a socket set, remove the bolts securing the U-joint to the driveshaft and differential.
3. Carefully slide the driveshaft out, ensuring not to damage the transmission output seal.

3. Replace U-Joint

Sub-steps:
1. Secure the U-joint in a vice or U-joint press and remove the retaining clips.
2. Remove the old U-joint from the yoke.
3. Lubricate the new U-joint with appropriate grease.
4. Install the new U-joint into the yoke, ensuring proper positioning.
5. Reinstall the retaining clips to secure the U-joint.

4. Reinstall Driveshaft

Sub-steps:
1. Align the driveshaft with the marks made during removal.
2. Secure the driveshaft to the differential and transmission using the original bolts.
3. Torque the bolts to the manufacturer’s specifications (generally 15-20 lb-ft, check specific values for your model).

5. Final Checks

Sub-steps:
1. Reconnect the battery.
2. Conduct a final inspection to ensure all connections are secure.
3. Lower the vehicle and perform a test drive to confirm the vibration has been resolved.
