Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and securely lifted using jack stands.
Disconnect the negative battery cable to prevent electrical issues.

2. Remove Driveshaft

Sub-steps:
1. Using a socket set, remove the bolts securing the driveshaft to the rear differential.
2. Mark the orientation of the driveshaft to ensure correct reinstallation.
3. Carefully pull the driveshaft away from the differential and slide it out of the transmission.

3. Remove U-Joints

Sub-steps:
1. Secure the driveshaft in a vice to prevent movement.
2. Using a U-joint removal tool, press out the U-joints from the yokes.
3. Clean the yoke surfaces with a wire brush to prepare for new U-joints.

4. Install New U-Joints

Sub-steps:
1. Apply grease to the new U-joints and place them into the yokes.
2. Use the U-joint tool to press the U-joint into place until fully seated.
3. Ensure that the retaining clips are securely in place.

5. Reinstall Driveshaft

Sub-steps:
1. Align the driveshaft with the markings made earlier and slide it back into the transmission.
2. Reattach the driveshaft to the rear differential using the original bolts, tightening them to the manufacturer's specified torque value (usually around 15-20 ft-lbs).

6. Final Checks

Sub-steps:
1. Reconnect the negative battery cable.
2. Start the vehicle and perform a test drive to ensure no vibrations or noises are present.
