Solution

1. Preparation

Ensure the vehicle is parked on a level surface and engage the parking brake.
Gather necessary tools and parts.

2. Remove Driveshaft

Sub-steps:
1. Disconnect the negative battery terminal to prevent electrical issues.
2. Use a floor jack and jack stands to lift the vehicle securely.
3. Locate the U-joint bolts and remove them using a socket set (specific size may vary).
4. Carefully slide the driveshaft out of the transmission and remove it from the vehicle.

3. Inspect and Replace U-joint

Sub-steps:
1. Inspect the U-joint for wear and damage. If replacement is necessary, use a U-joint puller to remove the old joint.
2. Clean the yoke and surrounding area to ensure a proper seal.
3. Install the new U-joint, ensuring it is seated correctly in the yoke.
4. Apply grease to the U-joint fittings as specified by the manufacturer.

4. Reinstall Driveshaft

Sub-steps:
1. Align the driveshaft back into the transmission and the rear differential.
2. Reattach the driveshaft using the original bolts, tightening them to the manufacturer's specified torque settings.
3. Reconnect the negative battery terminal.

5. Final Checks

Lower the vehicle and perform a final visual inspection of the U-joint and driveshaft.
Ensure all tools are removed from the work area.
