Solution

1. Preparation

Gather tools and parts required for the job.
Ensure the vehicle is parked on a level surface, and engage the parking brake.
Safety warning: Disconnect the battery before working on electrical systems.

2. Raise the Vehicle

Use a jack to lift the front or rear of the F-150 depending on the affected wheel.
Secure the vehicle with jack stands for safety.

3. Remove the Wheel

Use a lug wrench to loosen and remove the lug nuts.
Take off the wheel and set it aside.

4. Inspect and Replace the Wheel Bearing

Inspection:
- Remove the brake caliper and rotor to access the hub assembly.
- Check the wheel bearing for any signs of damage such as rust or play.
Replacement:
- Using a bearing puller, remove the old wheel bearing from the hub.
- Clean the hub area and install the new wheel bearing, ensuring it is seated properly.
- Reinstall the hub assembly and torque bolts to manufacturer specifications (typically around 85-100 ft-lbs, but check the service manual).

5. Reassemble and Lower the Vehicle

Reinstall the brake rotor and caliper.
Put the wheel back on and hand-tighten the lug nuts.
Lower the vehicle and then fully tighten the lug nuts in a crisscross pattern to the specified torque (usually 100-120 ft-lbs).

6. Test Drive

Conduct a test drive to confirm the noise has been resolved.
