Solution

1. Preparation

Tools Required: Jack and jack stands, socket set, torque wrench, wheel chocks, pry bar, and bearing puller.
Ensure the vehicle is on a flat surface and secure with wheel chocks.
Disconnect the negative terminal of the battery for safety.

2. Raise the Vehicle

Use a jack to lift the vehicle and place it securely on jack stands.
Remove the wheel where the noise is suspected using a socket set.

3. Remove the Brake Components

Sub-steps:
1. Remove the brake caliper by unbolting it and securing it away from the rotor using wire or a bungee cord.
2. Take off the brake rotor by removing any retaining screws or bolts. If necessary, use a pry bar to help detach it.

4. Inspect and Remove the Wheel Bearing

Sub-steps:
1. Visually inspect the wheel bearing for damage or wear. Look for discoloration, pitting, or roughness.
2. If replacement is needed, remove the hub assembly by unbolting it from the spindle.
3. Use a bearing puller to carefully extract the old wheel bearing from the hub assembly.

5. Install New Wheel Bearing

Sub-steps:
1. Clean the hub assembly and ensure no debris remains.
2. Install the new wheel bearing by pressing it into place using a bearing press or appropriate tools.
3. Reassemble the hub assembly to the spindle and torque the bolts to the manufacturer’s specifications.

6. Reassemble Brake Components and Wheel

Sub-steps:
1. Reattach the brake rotor and secure it with retaining screws or bolts.
2. Reinstall the brake caliper and ensure it is properly secured.
3. Mount the wheel back onto the hub and torque the lug nuts to the specified torque.

7. Lower the Vehicle

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