Solution

1. Preparation

Gather tools and safety equipment.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to ensure safety during the inspection.

2. Inspect Tires

Sub-steps:
1. Visually inspect all tires for bulges, uneven wear, or damage.
2. Measure tire pressure using a tire gauge and inflate to the manufacturer's recommended pressure if necessary.
3. Rotate tires if uneven wear is detected to promote even wear.

3. Wheel Balancing

Sub-steps:
1. Remove the wheels from the vehicle using a socket set.
2. Take the wheels to a tire shop for professional balancing.
3. Reinstall the wheels and torque lug nuts to the manufacturer's specifications (typically 80-100 ft-lbs).

4. Inspect Suspension

Sub-steps:
1. Visually inspect the suspension components, including control arms, struts, and bushings, for signs of wear or damage.
2. Use a pry bar to check for excessive play in ball joints and bushings.
3. Replace any worn or damaged components as necessary.

5. Wheel Alignment

Sub-steps:
1. Take the vehicle to a professional alignment shop.
2. Have a four-wheel alignment performed to ensure all wheels are aligned according to specifications.
3. Test drive the vehicle to confirm the vibration is resolved.
