Solution

1. Preparation

Tools Required: Jack and jack stands, wheel chocks, socket set, torque wrench, OBD-II scanner.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Disconnect the battery to prevent electrical shorts.

2. Inspect and Replace U-Joints

Sub-steps:
1. Remove the driveshaft by unbolting the flange at the differential and the transmission.
2. Inspect the U-joints for play by attempting to move them back and forth. If they are loose or rusted, proceed to replace them.
3. Use a U-joint press to remove the old U-joints.
4. Install new U-joints by pressing them into place and ensuring they are seated correctly.

3. Check and Replace Support Bearings

Sub-steps:
1. Locate the support bearings along the driveshaft.
2. Remove the bolts securing the support bearing and slide it off the driveshaft.
3. Inspect the bearing for wear or damage. If worn, replace it with a new bearing.
4. Install the new support bearing and secure it with the appropriate torque specification.

4. Balance the Driveshaft

Sub-steps:
1. If vibration persists, take the driveshaft to a professional shop for balancing.
2. Ensure the driveshaft is balanced correctly to prevent future vibrations.

5. Reinstall Driveshaft

Sub-steps:
1. Reattach the driveshaft to the differential and transmission using new gaskets if necessary.
2. Torque all bolts to the manufacturer's specifications.
3. Reconnect the battery.
