Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery (negative terminal) to ensure safety.

2. Lift the Vehicle

Use a jack to lift the vehicle and secure it with jack stands.
Remove the wheel by loosening the lug nuts with a socket wrench.

3. Remove the Brake Components

Remove the brake caliper by unbolting it from the bracket (use a torque wrench as specified in service manual).
Support the caliper using a bungee cord, ensuring the brake line is not stretched.
Remove the brake rotor by unbolting it from the hub (if applicable).

4. Inspect and Remove the Wheel Bearing

Remove the dust cap or axle nut carefully using appropriate tools.
Use a bearing puller to extract the bearing from the hub assembly.
Inspect the bearing for wear, pitting, or damage.

5. Install New Wheel Bearing

Clean the hub area thoroughly to ensure proper fitment.
Install the new wheel bearing using a bearing press or appropriate tools to avoid damage.
Torque the axle nut to the manufacturer’s specifications.

6. Reassemble Components

Reattach the brake rotor and caliper, ensuring all bolts are torqued correctly.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the specified value.

7. Final Checks

Reconnect the battery.
Test drive the vehicle to ensure the noise is eliminated and components function properly.
