Solution

1. Preparation

Tools Required: Jack and jack stands, socket set, torque wrench, punch, hammer, wheel bearing puller, grease, cleaning rags.
Safety Warnings:
- Ensure the vehicle is on a flat surface and secured with wheel chocks.
- Wear safety glasses and gloves during the procedure.

2. Lift the Vehicle

Loosen the lug nuts on the affected wheel slightly while the vehicle is on the ground.
Use a jack to lift the vehicle and secure it with jack stands.
Remove the wheel by fully loosening and removing the lug nuts.

3. Remove Brake Components

Remove the brake caliper by unscrewing the mounting bolts.
Hang the caliper using a bungee cord or suitable method to avoid straining the brake line.
Take off the brake rotor by removing any retaining screws and sliding it off the hub.

4. Remove the Hub Assembly

Remove the dust cap from the center of the wheel hub using a punch and hammer.
Remove the hub nut using a socket and wrench.
Use a wheel bearing puller to extract the hub assembly from the axle. Ensure the puller is securely attached, and apply pressure evenly to avoid damage.

5. Replace the Wheel Bearing

Remove the old wheel bearing from the hub assembly using a bearing press or appropriate tools.
Clean the hub assembly thoroughly.
Install the new wheel bearing into the hub, ensuring it is seated correctly.
Apply grease to the bearing and the assembly according to the manufacturer’s specifications.

6. Reassemble Components

Reinstall the hub assembly onto the axle and secure it with the hub nut, torquing it to the manufacturer’s specifications (typically around 150 ft-lbs).
Reattach the brake rotor and caliper, ensuring all bolts are tightened to the specified torque.
Reinstall the dust cap, ensuring it is seated properly.

7. Lower the Vehicle

Place the wheel back on and hand-tighten the lug nuts.
Lower the vehicle and then torque the lug nuts to the manufacturer’s specifications (usually around 76 ft-lbs).
