Solution

1. Preparation

Tools Required: Socket set, jack and jack stands, torque wrench, OBD-II scanner, wheel balancer.
Ensure the vehicle is on a level surface and engage the parking brake.

2. Tire Inspection and Rotation

Sub-steps:
- Remove wheel covers if applicable.
- Inspect each tire for uneven wear patterns, bulges, or punctures.
- Rotate the tires if uneven wear is identified.
- Reinflate tires to the manufacturer’s specified pressure.

3. Wheel Alignment and Balancing

Sub-steps:
- Use a wheel alignment machine to check and adjust alignment as necessary.
- Balance the tires using a wheel balancer if vibrations persist after alignment.

4. Driveshaft Inspection

Sub-steps:
- Raise the vehicle using a jack and secure it with jack stands.
- Inspect the driveshaft for any visible damage or bending.
- Check U-joints for wear; replace if they are loose or seized.

5. Engine and Transmission Mount Inspection

Sub-steps:
- Visually inspect engine and transmission mounts for cracks or separation.
- If any mounts are damaged, replace them with OEM parts.
- Tighten all mount bolts to the manufacturer’s torque specifications.

6. Test Drive

After completing the repairs, take the vehicle for a test drive to ensure the vibration issue has been resolved.
