Solution

1. Preparation

Tools Required: Jack and jack stands, socket set, grease gun, U-joint removal tool, safety goggles, gloves.
Ensure the vehicle is parked on a flat surface and engage the parking brake.

2. Lift the Vehicle

Use a jack to lift the rear of the vehicle.
Secure it with jack stands for safety.

3. Remove the Driveshaft

Sub-steps:
- 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 or rear differential.
- Make sure to mark the orientation of the driveshaft for reinstallation.

4. Inspect and Replace U-joints

Sub-steps:
- Check for any visible damage, wear, or excessive play in the U-joints.
- If replacement is necessary, use a U-joint removal tool to press out the old U-joint.
- Clean the area before installing the new U-joint and ensure that it is properly lubricated.
- Press the new U-joint into place, ensuring it is seated correctly.

5. Reinstall the Driveshaft

Sub-steps:
- Align the driveshaft with the marked position and slide it back into place.
- Reinstall the bolts and torque them to the manufacturer's specifications (usually around 30-40 ft-lbs, but refer to the service manual for specifics).
