Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and secure with wheel chocks.
Lift the vehicle using a jack and support it with jack stands.

2. Remove Driveshaft

Disconnect the Battery: Disconnect the negative terminal to prevent electrical shorts.
Remove Bolts: Using a socket set, remove the bolts securing the driveshaft to the rear differential and transmission. Keep the bolts for reinstallation.
Support the Driveshaft: Use a suitable support to hold the driveshaft in place while working on the U-joints.
Slide the Driveshaft Off: Carefully slide the driveshaft from the U-joints, noting its orientation for reinstallation.

3. Replace U-Joints

Remove the U-Joint Clips: Use needle-nose pliers to remove retaining clips or snap rings from the U-joint.
Press Out Old U-Joint: Using a U-joint press, carefully press out the old U-joint from the driveshaft.
Install New U-Joint: Lubricate the new U-joint with grease and insert it into the driveshaft. Press it in place until it seats fully.
Reinstall Clips: Secure the new U-joint with retaining clips or snap rings.

4. Reinstall Driveshaft

Align the Driveshaft: Position the driveshaft back into its original orientation.
Secure Bolts: Reinstall the bolts to the rear differential and transmission, tightening them to the manufacturer’s torque specifications (usually around 18-22 ft-lbs, but confirm with specifications).
Reconnect Battery: Reconnect the negative terminal of the battery.

5. Final Checks

Lower the vehicle and perform a test drive to ensure that all symptoms are resolved.
