Using a socket, remove the bolts securing the driveshaft to the differential and the transmission.
Carefully lower the driveshaft from the vehicle and secure it on a workbench.

3. Inspect and Replace U-joints

Tools Required: U-joint removal tool, grease gun, snap ring pliers.
Remove the snap rings from the U-joint using the snap ring pliers.
Use the U-joint removal tool to press the U-joint out of the yoke.
Insert the new U-joint into the yoke, ensuring it is properly aligned.
Reinstall the snap rings to secure the U-joint in place.
