Solution

1. Tire Inspection and Replacement

Sub-steps:
- Remove all four wheels using a socket set.
- Inspect tires for uneven wear, bulges, or cuts; replace if necessary.
- Ensure tires are of the correct size and type for the vehicle.

2. Balancing Tires

Sub-steps:
- Mount the tires on a tire balancing machine.
- Identify the amount of weight needed to balance each tire.
- Attach weights to the rim as indicated by the machine.
- Reinstall balanced tires onto the vehicle and torque lug nuts to the manufacturer's specification (typically around 90 ft-lbs).

3. Suspension Component Inspection

Sub-steps:
- With the vehicle lifted, inspect all suspension components for wear or damage.
- Replace any worn tie rods, ball joints, or control arms as necessary.
- Ensure all fasteners are tightened to manufacturer specifications.

4. Wheel Alignment Adjustment

Sub-steps:
- Use an alignment machine to check camber, caster, and toe settings.
- Adjust the alignment as needed to bring it within factory specifications.
- Test drive to ensure the vehicle tracks straight.
