Solution

1. Preparation

Gather tools and parts necessary for repair.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Wear safety glasses and gloves during the procedure.

2. Lift the Vehicle

Use a hydraulic jack to lift the rear of the vehicle.
Secure the vehicle with jack stands to ensure stability.

3. Remove Driveshaft

Tools Required: Socket set, torque wrench, U-joint puller (if necessary).
Remove the bolts securing the driveshaft to the U-joint using the socket set.
Carefully slide the driveshaft off the U-joint. Mark the orientation of the driveshaft for reinstallation.

4. Inspect and Replace U-Joint

Check the U-joint for signs of wear, such as rust, excessive play, or damaged bearings.
If replacement is needed, use a U-joint puller to remove the old U-joint from the driveshaft.
Install the new U-joint by aligning it properly and pressing it into place until it is seated.

5. Reinstall Driveshaft

Reattach the driveshaft to the U-joint, ensuring it is aligned with the marks made earlier.
Use the torque wrench to tighten the bolts to the manufacturer's specified torque settings.

6. Lower Vehicle and Test

Carefully remove the jack stands and lower the vehicle.
Test drive the vehicle to confirm the repair was successful and listen for any residual noise.
