Solution

1. Preparation

Tools Required:
- Floor jack and jack stands
- Wrench set and socket set
- Torque wrench
- Grease gun (if re-greasing)
- Replacement U-joint (if necessary)

2. Lift the Vehicle

Safely lift the vehicle using a floor jack.
Secure the vehicle on jack stands to ensure stability.

3. Remove the Driveshaft

Using the appropriate sockets, remove the bolts securing the driveshaft to the U-joint.
Carefully slide the driveshaft off the U-joint, ensuring to keep track of any washers or spacers.

4. Inspect the U-joint

Check for signs of wear, such as excessive play or rust.
If the U-joint is damaged, proceed to replace it.

5. Replace the U-joint

If replacing, remove the retaining clips from the U-joint.
Use a press or hammer to push the old U-joint out and install the new one, ensuring it is seated properly.
Reinstall the retaining clips securely.

6. Reassemble the Driveshaft

Reattach the driveshaft to the U-joint.
Torque the bolts to the manufacturer’s specifications (typically around 30-50 lb-ft but verify for your specific model).

7. Re-grease (if applicable)

If the U-joint is of a serviceable type, use a grease gun to apply grease to the new U-joint.

8. Lower the Vehicle

Carefully remove the jack stands and lower the vehicle back to the ground.
