Sub-steps:
1. Check each U-joint for any signs of wear, such as rust or play in the joints.
2. Rotate the U-joints to check for smooth movement without binding.
3. If any issues are found, proceed to replace the affected U-joint.

4. Replace U-joints (if necessary)

Sub-steps:
1. Remove retaining clips or straps securing the U-joint using pliers.
2. Use a press (or a hammer and socket) to remove the old U-joint from the driveshaft.
3. Lubricate the new U-joint and insert it into the driveshaft.
4. Reinstall retaining clips or straps to secure the new U-joint.

5. Reinstall Driveshaft

Sub-steps:
1. Align the driveshaft with the transmission and rear differential, ensuring it is properly seated.
2. Reinstall the bolts and torque them to the manufacturer's specifications (typically between 15-30 ft-lbs).
3. Lower the vehicle and perform a test drive to ensure proper operation.
