Solution

1. Tire Inspection

Sub-steps:
1. Remove the wheel covers if applicable.
2. Inspect each tire for bulges, cracks, or uneven tread wear.
3. Replace any damaged tires with new ones.

2. Tire Pressure Adjustment

Sub-steps:
1. Use a tire pressure gauge to measure each tire's pressure.
2. Inflate tires to the manufacturer-recommended pressure (found in the owner’s manual or on the driver’s door jamb).
3. Recheck pressure after adjusting.

3. Suspension Component Inspection

Sub-steps:
1. Lift the vehicle using a jack and secure with jack stands.
2. Visually inspect control arms, tie rods, and bushings for cracks or play.
3. Replace any worn or damaged components as necessary.

4. Wheel Alignment

Sub-steps:
1. Take the vehicle to a professional alignment shop.
2. Have the technician perform a four-wheel alignment.
3. Ensure the alignment is within manufacturer specifications.

5. Wheel Balancing

Sub-steps:
1. Remove the wheels from the vehicle.
2. Place each wheel on a tire balancing machine.
3. Add weights as needed to achieve proper balance.
4. Reinstall the wheels and torque to the manufacturer’s specifications (typically 80-100 ft-lbs).
