Solution

1. Preparation

Gather tools and parts required for the job.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to ensure safety.

2. Raise the Vehicle

Use a jack to lift the front or rear of the Mustang, depending on which wheel bearings are being replaced.
Secure the vehicle with jack stands for safety.

3. Remove the Wheel

Use a lug wrench to loosen the lug nuts.
Remove the lug nuts entirely and take off the wheel.

4. Remove the Brake Components

Remove the caliper by unbolting it from the bracket. (Use a 13mm or 15mm socket depending on the model)
Secure the caliper to the suspension using a bungee cord to prevent strain on the brake line.
Remove the brake rotor by unscrewing the retaining screws if applicable.

5. Replace the Wheel Bearing

Remove the hub assembly by unbolting it from the steering knuckle (typically requires a 30mm socket).
Use a bearing puller if necessary to detach the old wheel bearing.
Clean the hub area thoroughly before installing the new bearing.
Install the new wheel bearing into the hub, ensuring it is seated properly.

6. Reassemble the Components

Reattach the hub assembly to the steering knuckle and torque to the manufacturer's specification (usually around 85-100 ft-lbs).
Reinstall the brake rotor and caliper, ensuring all bolts are tightened to spec.
Reinstall the wheel and hand-tighten the lug nuts.

7. Lower the Vehicle

Carefully lower the vehicle back to the ground and remove the jack stands.
Tighten the lug nuts to the manufacturer's torque specification (typically 100-110 ft-lbs).
