Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the ignition is off.
Disconnect the battery to avoid electrical issues.

2. Raise Vehicle

Use a hydraulic jack to lift the front or rear of the vehicle, depending on which wheel bearing is suspected to be faulty.
Secure the vehicle with jack stands to ensure stability.

3. Remove Wheel

Use a lug wrench to loosen and remove the lug nuts.
Carefully take off the wheel and set it aside.

4. Remove Brake Components

Remove the brake caliper by unscrewing the caliper bolts using a socket set.
Hang the caliper using a bungee cord to avoid straining the brake line.
Remove the brake rotor by unscrewing any retaining screws and pulling it off the hub.

5. Remove Wheel Bearing Assembly

Unscrew the wheel bearing retaining nuts using a torque wrench, taking care to note the torque specifications for reinstallation.
Remove the wheel bearing assembly from the hub using a bearing puller if necessary.

6. Install New Wheel Bearing

Clean the hub area where the new wheel bearing will be installed.
Press or install the new wheel bearing into the hub assembly, ensuring it’s seated properly.
Reinstall the retaining nuts and torque them to the manufacturer's specifications.

7. Reassemble Components

Reinstall the brake rotor and secure it with retaining screws.
Reattach the brake caliper and tighten the caliper bolts to the specified torque.
Reinstall the wheel and tighten the lug nuts in a crisscross pattern to ensure even pressure.

8. Lower Vehicle

Carefully remove the jack stands and lower the vehicle back to the ground.
