Ensure the vehicle is parked on a flat surface and the engine is off.
Lift the vehicle using a jack and secure it with jack stands.

2. Tire Balancing

Sub-steps:
- Remove the affected wheel(s).
- Mount the wheel on a tire balancer.
- Follow the balancer's instructions to add weights to the rim.
- Reinstall the wheel and torque the lug nuts to the manufacturer’s specifications (typically 80-100 ft-lbs for F-150).

3. Wheel Alignment

Sub-steps:
- Position the vehicle on an alignment rack.
- Adjust the camber, caster, and toe settings to match manufacturer specifications.
- Tighten all adjustment bolts securely.

4. Inspect and Replace Suspension Components (if necessary)

Sub-steps:
- Visually inspect all suspension parts for wear or damage.
- Replace any worn bushings, control arms, or shocks with new parts.
- Use a torque wrench to secure new components to the specified torque values.

5. Driveshaft Inspection

Sub-steps:
- Check the driveshaft for any visible signs of damage or bends.
- If damaged, replace the driveshaft with an OEM part.
- Ensure all mounting points are secure and lubricated as needed.

6. Wheel Bearing Inspection

Sub-steps:
- Raise the vehicle and remove the wheel.
- Inspect the wheel bearing for signs of wear or roughness.
- If necessary, replace the wheel bearing by removing the hub assembly and pressing in a new bearing.
