Solution

1. Preparation

Gather tools: jack, jack stands, wheel chocks, lug wrench, socket set, impact wrench (optional), torque wrench, and bearing puller.
Ensure safety by wearing gloves and safety glasses.

2. Remove Wheel

Loosen the lug nuts with the lug wrench.
Raise the vehicle using the jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Remove Brake Components

Remove the caliper by unscrewing the caliper bolts using the socket set.
Support the caliper with a bungee cord or wire to avoid hanging on the brake line.
Remove the brake rotor if necessary, ensuring no rust or debris affects bearing access.

4. Inspect and Replace Wheel Bearing

Remove the dust cap (if applicable) to expose the hub nut.
Use an impact wrench or socket set to remove the hub nut.
Pull the wheel hub assembly away from the steering knuckle, taking care not to damage surrounding components.
Use a bearing puller to remove the old bearing from the hub.
Clean the hub assembly and install the new bearing, ensuring it is seated correctly.

5. Reassemble Components

Reattach the hub assembly to the steering knuckle and torque the hub nut to manufacturer specifications (typically around 150 Nm, but refer to specific service manual).
Reinstall the brake rotor and caliper, ensuring caliper bolts are torqued properly.
Reinstall the wheel and hand-tighten the lug nuts.

6. Lower Vehicle and Final Checks

Lower the vehicle from the jack stands and remove the jack.
Tighten lug nuts to manufacturer’s torque specifications (usually 120 Nm).
Perform a final inspection for any loose components or abnormalities.
