Solution

1. Preparation

Tools Required: Socket set, torque wrench, U-joint puller, grease gun, safety glasses, gloves.
Raise the vehicle using a jack and secure it with jack stands.
Disconnect the battery to prevent electrical issues during repairs.

2. Remove Driveshaft

Loosen Bolts: Using a socket set, loosen and remove the bolts securing the driveshaft to the U-joints at both the front and rear ends.
Detach Driveshaft: Carefully slide the driveshaft out of the transmission and rear differential.
Inspect for Damage: Check the driveshaft for any signs of damage or imbalance as you remove it.

3. Replace U-Joints

Remove Old U-Joint: Use a U-joint puller to remove the faulty U-joint from the driveshaft.
Clean Surfaces: Clean the area where the new U-joint will be installed to ensure a proper fit.
Install New U-Joint: Position the new U-joint into the driveshaft, ensuring it is aligned correctly.
Secure U-Joint: Use the U-joint puller to press the new joint into place. Ensure it is seated properly.

4. Reinstall Driveshaft

Reconnect Driveshaft: Align the driveshaft with the transmission and rear differential. Slide it into place carefully.
Torque Bolts: Reattach the bolts and torque them to the manufacturer's specifications (typically around 30-40 ft-lbs).
Recheck Alignment: Ensure the driveshaft is aligned correctly and there is no binding.

5. Final Checks

Grease U-Joint: Use a grease gun to apply grease to the new U-joint until it begins to ooze out of the seals.
Reconnect Battery: Reconnect the battery once all work is complete.
Lower Vehicle: Carefully remove jack stands and lower the vehicle back to the ground.
