Solution

1. Preparation

Gather Tools:
- Jack and jack stands
- Lug wrench
- Torque wrench
- Socket set
- Wheel bearing puller kit
Safety Warning: Always ensure the vehicle is on a flat surface and securely raised on jack stands before working on it.

2. Remove Wheel

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

3. Access Wheel Hub

Remove the brake caliper by unbolting it from the mounting bracket. Suspend it with a bungee cord to avoid stress on the brake line.
Remove the brake rotor by unscrewing any retaining screws or bolts.

4. Inspect and Replace Wheel Bearing

Check for Damage: Inspect the wheel bearing for any signs of wear or damage.
If replacement is needed, detach the wheel hub from the steering knuckle by removing the bolts using a socket set.
Use a wheel bearing puller to carefully extract the old bearing from the hub.
Clean the hub and apply new grease to the new bearing before installation.
Press the new bearing into the hub using the wheel bearing press or appropriate tools.

5. Reassemble Components

Reattach the wheel hub to the steering knuckle and torque the bolts to the manufacturer’s specifications (typically around 100-120 Nm, but verify with service manual).
Reinstall the brake rotor and caliper.
Place the wheel back onto the hub, hand-tighten the lug nuts, then lower the car and torque the lug nuts to specification.
