Solution

1. Tire Inspection and Replacement

Sub-steps:
- Check tire pressure with a tire gauge; inflate to the manufacturer's recommended PSI if necessary.
- Inspect each tire for visible punctures, bulges, or uneven wear.
- Replace any damaged tires with new ones, ensuring they are the correct size for the vehicle.

2. Wheel Balancing

Sub-steps:
- Remove the wheels from the vehicle using a socket set.
- Mount the wheels on a tire balancing machine to identify imbalances.
- Add or adjust weights to achieve proper balance, then re-install the wheels on the vehicle.

3. Suspension and Steering Component Inspection

Sub-steps:
- Lift the vehicle using a jack and secure it with jack stands.
- Inspect control arms, tie rods, and bushings for wear; replace any worn components.
- Tighten any loose bolts or fasteners as specified in the service manual.

4. Wheel Alignment

Sub-steps:
- Take the vehicle to a professional alignment shop or perform a DIY alignment if equipped with the necessary tools.
- Adjust camber, caster, and toe settings to meet the specifications for the F-150.
- Test drive the vehicle post-alignment to ensure the issue is resolved.

5. Driveshaft Inspection

Sub-steps:
- Inspect the driveshaft for any visible damage or signs of rust.
- Check the U-joints for play by attempting to move them by hand; if they are loose, replace them.
- Ensure that the driveshaft is properly secured and aligned.
