Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, socket set, torque wrench, wheel bearing grease, and a dial indicator (if checking for runout).
Safety Warnings: Ensure the vehicle is on a flat surface and securely supported with jack stands before working underneath.

2. Remove Wheel

Loosen the lug nuts with a lug wrench.
Jack up the vehicle and securely place it on jack stands.
Remove the lug nuts completely and take off the wheel.

3. Access the Wheel Bearings

Remove the brake caliper by unscrewing the caliper bolts (typically require a socket).
Hang the caliper using a wire or bungee cord to avoid stress on the brake line.
Remove the brake rotor from the hub.

4. Inspect and Replace Wheel Bearings

Remove any dust cover or retaining ring to access the wheel bearings.
Inspect the bearings for wear, pitting, or discoloration.
If replacement is necessary, use a bearing puller to remove the old bearings from the hub assembly.
Clean the bearing race and apply new wheel bearing grease to the new bearings.
Install the new bearings and secure any retaining rings or dust covers.

5. Reassemble Components

Reinstall the brake rotor and ensure it is seated correctly.
Reattach the brake caliper and torque the caliper bolts to manufacturer's specifications.
Reinstall the wheel and hand-tighten the lug nuts.

6. Lower Vehicle and Finalize

Lower the vehicle back to the ground and torque the lug nuts to the proper specification (typically 75-100 ft-lbs for F-150).
Perform a final inspection of the wheel assembly for any loose components.
