Disconnect the battery to ensure safety during repairs.

2. Lift the Vehicle

Use a hydraulic jack to lift the vehicle and secure it on jack stands.
Ensure the vehicle is stable before proceeding.

3. Inspect and Replace Driveshaft Components

Inspect U-joints and CV joints:
- Remove the driveshaft by unbolting it from the differential and transmission.
- Carefully examine the U-joints for play or wear. If damaged, replace them.
Replace driveshaft if necessary:
- If the driveshaft is bent or damaged beyond repair, replace it with a new unit.
- Ensure to use OEM or high-quality aftermarket parts for replacement.

4. Reinstallation

Reinstall the driveshaft by aligning it correctly with the transmission and differential.
Torque the bolts to the manufacturer's specifications (check the service manual for exact torque values).
Recheck the installation of U-joints and ensure they are seated properly.

5. Reconnect Battery and Lower Vehicle

Once all components are secured, reconnect the battery.
Carefully lower the vehicle from the jack stands.

6. Test Drive

Conduct a test drive to verify that the vibration issue has been resolved.
Monitor for any unusual noises or vibrations during various speeds and conditions.
