Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and secure it with wheel chocks.
Disconnect the battery to avoid any electrical issues.

2. Inspect and Replace Driveshaft Components

2.1 Visual Inspection

Check the driveshaft for visible damage.
Look for signs of oil leaks around seals.

2.2 U-Joint Inspection

Remove the driveshaft from the vehicle (mark its position to ensure proper reinstallation).
Inspect U-joints for play and stiffness; replace if any wear is detected.
- Tools Required: Socket set, U-joint puller.

2.3 Center Support Bearing Replacement

Remove the center support bearing by unscrewing the mounting bolts.
Replace the bearing and ensure it is properly aligned.
- Tools Required: Socket set, torque wrench.
- Torque Specs: Refer to the service manual for specific torque values.

2.4 Reinstall Driveshaft

Reinstall the driveshaft, ensuring it is aligned with the marks made during removal.
Tighten all bolts to the specified torque settings.

3. Road Test

Reconnect the battery.
Perform a test drive to ensure the vibration has been eliminated.
