Solution

1. Preparation

Tools Required: Socket set, jack stands, wheel chocks, torque wrench, grease gun.
Safely lift the vehicle using a hydraulic jack and secure it with jack stands.
Disconnect the battery to prevent electrical issues during repair.

2. Remove the Driveshaft

Sub-steps:
1. Using a socket set, remove the bolts securing the driveshaft to the rear differential and transmission.
2. Carefully slide the driveshaft out of the U-joint, ensuring not to damage any seals or gaskets.
3. Support the driveshaft with a suitable prop while disconnecting.

3. Inspect and Replace U-Joints

Sub-steps:
1. Identify the U-joint needing replacement and mark its orientation for reinstallation.
2. Use a U-joint removal tool or press to extract the old U-joint from the driveshaft.
3. Clean the U-joint yoke thoroughly and inspect for any wear or damage.
4. Insert the new U-joint, ensuring it is properly aligned with the marked orientation.
5. Secure the new U-joint using the U-joint tool to press it into place.

4. Reinstall the Driveshaft

Sub-steps:
1. Slide the driveshaft back into position, aligning it with the transmission and rear differential.
2. Reinstall and torque the bolts to the manufacturer’s specifications (typically around 30-45 ft-lbs, check specific values).
3. Reconnect the battery and ensure no tools are left in the engine bay.

5. Lubricate the U-Joint

Sub-steps:
1. Using a grease gun, apply the appropriate grease to the new U-joint until grease begins to ooze from the seals.
2. Wipe off any excess grease to avoid attracting dirt and debris.
