Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface, and engage the parking brake.
Disconnect the negative battery terminal to avoid electrical shorts.

2. Lift the Vehicle

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

3. Remove the Wheel

Using a socket set, loosen and remove the lug nuts from the wheel.
Take off the wheel and inspect the brake components.

4. Remove the Brake Components

Detach the brake caliper by removing the caliper mounting bolts. Suspend the caliper using a wire to avoid strain on the brake line.
Remove the brake rotor by sliding it off the hub.

5. Remove the Wheel Bearing

Depending on the design, remove any retaining clips or bolts securing the wheel bearing assembly.
Use a puller tool to extract the wheel bearing from the hub.

6. Install New Wheel Bearing

Clean the hub area thoroughly, removing any debris or old grease.
Install the new wheel bearing, making sure it is seated properly.
Reattach any retaining clips or bolts according to manufacturer specifications (consult service manual for torque values).

7. Reassemble Components

Reinstall the brake rotor and caliper; ensure that all bolts are torqued to specifications.
Reattach the wheel and lug nuts, tightening them in a crisscross pattern to ensure even pressure.

8. Lower the Vehicle

Carefully remove the jack stands and lower the vehicle back to the ground.
Reconnect the negative battery terminal.
