Solution

1. Preparation

Tools Required: Jack and jack stands, wheel chocks, lug wrench, torque wrench, and socket set.
Ensure the vehicle is on a flat surface and the engine is turned off. Disconnect the battery if needed for safety.

2. Remove Wheel

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

3. Remove Brake Components

Tools Required: Socket set.
Remove the brake caliper by unscrewing the caliper bolts.
Secure the caliper to the suspension using a wire or bungee cord to avoid stress on the brake line.
Remove the brake rotor for access to the wheel bearing.

4. Inspect and Replace Wheel Bearing

Tools Required: Bearing puller, impact wrench (if necessary).
Inspect the wheel bearing for any signs of wear or damage.
If replacement is needed, use a bearing puller to remove the old bearing from the hub.
Clean the hub area thoroughly before installing the new bearing.
Install the new wheel bearing using the appropriate tools, ensuring it is seated properly.

5. Reassemble Components

Reinstall the brake rotor and caliper, ensuring bolts are torqued to the manufacturer’s specifications.
Reinstall the wheel and hand-tighten the lug nuts.

6. Lower Vehicle and Finalize

Lower the vehicle back to the ground and fully tighten the lug nuts in a criss-cross pattern using a torque wrench.
Reconnect the battery if it was disconnected.
