Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and securely supported.
Tools Required: Jack, jack stands, socket set, torque wrench, wheel chocks.

2. Remove Wheel

Loosen the lug nuts slightly while the vehicle is still on the ground.
Jack up the vehicle and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Remove Brake Components

Remove the brake caliper by unscrewing the caliper bolts. Hang it using a bungee cord to avoid stress on the brake line.
Remove the brake rotor by sliding it off the hub.

4. Inspect and Replace Wheel Bearings

Inspection: Examine the bearing for signs of wear or damage.
Removal: If replacement is needed, remove the dust cap (if applicable) and use a bearing puller to extract the old bearing from the hub.
Installation: Clean the hub thoroughly. Press the new bearing into place using a bearing press or appropriate tool, ensuring it's seated fully.

5. Reassemble

Reinstall the brake rotor and caliper.
Reattach the wheel, hand-tighten the lug nuts, lower the vehicle, and torque the lug nuts to the manufacturer’s specifications.
