Solution

1. Preparation

Gather tools: jack, jack stands, torque wrench, tire pressure gauge, wheel alignment tool.
Ensure the vehicle is parked on a flat surface and turn off the ignition.

2. Tire Inspection and Maintenance

Sub-steps:
- Remove the wheel covers (if applicable) using a flat tool.
- Inspect tires for any bulges, cracks, or foreign objects.
- Use a tire pressure gauge to check each tire's pressure; inflate or deflate to recommended PSI.
- Rotate the tires if uneven wear is detected.

3. Wheel Balancing

Sub-steps:
- Remove the wheels using a socket wrench.
- Take the wheels to a tire shop for professional balancing or use a wheel balancer if available.
- Reinstall wheels and torque lug nuts to the manufacturer’s specifications (typically 100-120 ft-lbs).

4. Wheel Alignment

Sub-steps:
- Use an alignment tool to check the angles of the wheels.
- Adjust camber, caster, and toe settings according to manufacturer specifications.
- Test drive to ensure adjustments have resolved the vibration issue.

5. Suspension Inspection

Sub-steps:
- Inspect shocks, struts, and bushings for any signs of wear or damage.
- Replace any worn components as necessary.
- Reassemble any components removed for inspection.
