Solution

1. Preparation

Tools Required:
- Floor jack
- Jack stands
- Socket set
- Torque wrench
- OBD-II scanner
Raise the vehicle using a floor jack and secure it with jack stands.
Ensure the vehicle is on a flat surface and the parking brake is engaged.

2. Inspect Driveshaft

Remove any covers or shields obstructing access to the driveshaft.
Visually inspect the driveshaft for cracks, bends, or corrosion.
Check the U-joints for free movement; replace if there is any play or binding.

3. Replace U-joints (if necessary)

Tools Required:
- U-joint removal tool
Remove the driveshaft from the vehicle.
Using the U-joint removal tool, carefully extract the faulty U-joints.
Install new U-joints, ensuring they are oriented correctly.
Reinstall the driveshaft, tightening bolts to the manufacturer’s torque specifications.

4. Balance and Align Wheels

Tools Required:
- Wheel balancer
- Alignment equipment
Mount the tires on a wheel balancer and check for imbalance.
Adjust weights as needed to achieve proper balance.
Perform a four-wheel alignment to ensure proper handling and tire wear.

5. Test Drive

Lower the vehicle from the jack stands and take it for a test drive.
Monitor for any remaining vibrations or noises during acceleration and deceleration.
