Solution

1. Preparation

Tools Required: Jack, jack stands, socket set, torque wrench, mechanic's stethoscope (optional), and safety glasses.
Safety Warnings: Ensure the vehicle is on a level surface and secured with jack stands before working underneath.

2. Remove Wheel

Loosen the lug nuts on the wheel using a socket set.
Lift the vehicle and remove the lug nuts completely.
Remove the wheel to gain access to the brake assembly and wheel hub.

3. Inspect and Replace Bearing

Visual Inspection: Examine the wheel hub and bearing for signs of wear or damage.
Remove Brake Caliper: Use a socket set to remove the brake caliper and secure it away from the rotor (do not hang it by the brake line).
Remove Brake Rotor: If necessary, remove the brake rotor to access the wheel bearing.
Remove Wheel Hub Assembly: Unbolt the wheel hub assembly from the steering knuckle using the appropriate socket size.
Press Out Old Bearing: Use a bearing press to remove the old bearing from the hub if it is pressed in.
Install New Bearing: Press in the new wheel bearing into the hub assembly carefully, ensuring it is seated correctly.

4. Reassemble Components

Reinstall Wheel Hub: Secure the wheel hub back onto the steering knuckle using the manufacturer’s torque specifications.
Reinstall Brake Rotor: Attach the brake rotor and ensure it is properly aligned.
Reinstall Brake Caliper: Mount the brake caliper back onto the rotor and tighten the caliper bolts to the specified torque.
Reattach Wheel: Place the wheel back onto the hub and hand-tighten the lug nuts.

5. Lower Vehicle and Final Checks

Lower the vehicle from the jack stands.
Tighten the lug nuts to the manufacturer’s specifications using a torque wrench.
Conduct a test drive to ensure the noise has been resolved.
