Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and secured with wheel chocks.
Disconnect the negative battery terminal to prevent electrical issues.

2. Raise the Vehicle

Use a hydraulic jack to lift the rear end of the vehicle.
Securely place jack stands under the frame to support the vehicle.

3. Remove the Driveshaft

Tools Required: Socket set, torque wrench, universal joint puller.
Loosen and remove the bolts securing the driveshaft to the differential and transmission.
Carefully slide the driveshaft out of the U-joint and set it aside.

4. Replace the U-Joint

Tools Required: U-joint press, grease gun, safety glasses.
Using the U-joint press, remove the old U-joint by pressing it out of the yoke.
Clean the yoke and inspect for any damage; replace if necessary.
Insert the new U-joint into the yoke, ensuring it is aligned correctly.
Secure the U-joint by pressing it into place, ensuring it is seated properly.

5. Reinstall the Driveshaft

Align the driveshaft with the U-joint and slide it back into place.
Reattach the driveshaft to the differential and transmission using the original bolts.
Torque the bolts to the manufacturer's specifications, typically around 15-20 ft-lbs.

6. Lubricate the U-Joint

Use a grease gun to apply appropriate grease to the new U-joint, ensuring it is well-lubricated.

7. Lower the Vehicle

Carefully remove the jack stands and lower the vehicle back to the ground.
Reconnect the negative battery terminal.
