Solution

1. Preparation

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

2. Tire Inspection

Sub-steps:
- Use the tire pressure gauge to check all tires' pressure and inflate them to the recommended PSI.
- Inspect each tire for bulges, cracks, or uneven wear patterns.
- If any tire is damaged, replace it with a new one.

3. Wheel Balancing

Sub-steps:
- Remove the wheel from the vehicle using the jack and jack stands.
- Take the wheel to a tire shop to have it balanced.
- Reinstall the wheel and torque the lug nuts to the manufacturer's specifications (typically 70-80 ft-lbs).

4. Suspension and Alignment Check

Sub-steps:
- Visually inspect all suspension components for signs of wear or damage; replace any faulty parts.
- Use the wheel alignment tool to check alignment settings; adjust as needed according to manufacturer specifications.

5. Test Drive

After completing repairs, take the vehicle for a test drive to monitor for any vibrations at high speeds.
