Solution

1. Preparation

Ensure the vehicle is parked on a flat surface and secure it with wheel chocks.
Disconnect the battery to avoid electrical issues during the repair.

2. Raise the Vehicle

Use a hydraulic jack to lift the rear of the vehicle.
Securely position jack stands under the vehicle to ensure stability.

3. Remove Driveshaft

Using a socket set, remove the bolts connecting the driveshaft to the differential and the transmission.
Carefully slide the driveshaft out of its mounting points.
Note the orientation of the driveshaft for reinstallation.

4. Inspect and Replace U-Joint

Remove the U-joint retaining clips using pliers or a small screwdriver.
Use a press or a hammer to carefully remove the U-joint from the driveshaft yoke.
Clean the yoke surfaces thoroughly.
Install the new U-joint by pressing it into place, ensuring it is seated properly.
Reinstall the retaining clips to secure the U-joint in place.

5. Reinstall Driveshaft

Align the driveshaft with the original markings and slide it back into position.
Reattach the driveshaft to both the differential and transmission using the original bolts.
Torque the bolts to the manufacturer’s specifications (typically around 30-40 ft-lbs, but verify for your specific model).

6. Lower the Vehicle

Remove the jack stands and carefully lower the vehicle using the hydraulic jack.
Reconnect the battery.
