Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a flat surface, engage the parking brake, and put on safety glasses.
Disconnect the negative battery terminal to avoid electrical issues.

2. Raise the Vehicle

Use a hydraulic jack to lift the rear of the vehicle and secure it on jack stands.
Ensure the vehicle is stable before working underneath.

3. Remove Driveshaft

Use a socket set to remove the bolts securing the driveshaft to the rear differential and transmission.
Carefully slide the driveshaft out of the transmission, ensuring to mark its original position for reinstallation.

4. Inspect and Replace U-joint

Remove any retaining clips or bolts securing the U-joint using a hammer and a U-joint removal tool or a socket.
Carefully press out the old U-joint from the yoke using a vise or U-joint tool.
Lubricate and install the new U-joint, ensuring it is seated properly in the yoke.
Reinstall retaining clips or bolts and ensure they are securely fastened.

5. Reinstall Driveshaft

Align the driveshaft with the marked position and slide it back into the transmission.
Reinstall the bolts to the rear differential and transmission, tightening them to the manufacturer's torque specifications (usually specified in the service manual).

6. Lower Vehicle and Test

Remove jack stands and lower the vehicle back to the ground.
Reconnect the negative battery terminal.
Start the vehicle and take it for a test drive to verify that the issue has been resolved.
