Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to prevent any electrical issues during the process.

2. Lift the Vehicle

Use a jack to lift the rear of the vehicle and secure it with jack stands.
Ensure the vehicle is stable before proceeding.

3. Remove the Driveshaft

Mark the position of the driveshaft on the differential and the transmission for reinstallation alignment.
Use a socket set to remove the bolts securing the U-joint to the driveshaft and differential.
Carefully slide the driveshaft off the U-joint.

4. Replace the U-joint

Use a U-joint removal tool or a press to remove the old U-joint from the driveshaft.
Clean the U-joint area thoroughly before installation.
Insert the new U-joint and ensure it is properly seated.
Secure the new U-joint with the retaining clips provided.

5. Reinstall the Driveshaft

Align the driveshaft with the marks made during removal.
Reattach the driveshaft to the differential and transmission using the original bolts. Tighten to manufacturer specifications (typically around 30-35 ft-lbs).
Ensure all fasteners are secure and check for proper alignment.

6. Lower the Vehicle

Remove jack stands and carefully lower the vehicle back to the ground.
Reconnect the battery.
