Solution

1. Tire Inspection and Balancing

Sub-steps:
- Remove the wheel covers (if applicable) and loosen lug nuts.
- Raise the vehicle using a jack and secure it with jack stands.
- Remove the wheel and inspect the tire for uneven wear, bulges, or punctures.
- If tires are damaged, replace them. If not, proceed to balance them using a tire balancer.
- Reinstall the wheel and torque the lug nuts to the manufacturer's specifications (typically around 80-100 ft-lbs).

2. Wheel Alignment

Sub-steps:
- Use an alignment machine to check the alignment specifications.
- Adjust the toe, camber, and caster as needed to bring them within manufacturer specifications.
- Test drive the vehicle again to ensure vibrations have been resolved.

3. Driveshaft and CV Joint Inspection

Sub-steps:
- Inspect the driveshaft for any signs of damage or bending; replace if necessary.
- Check CV joints for grease leaks or wear; replace any damaged CV joints.
- Ensure all fasteners are secure and in good condition.
