Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is securely lifted and supported.
Disconnect the negative battery terminal for safety.

2. Remove Wheel and Brake Components

Sub-steps:
1. Loosen the lug nuts using a lug wrench before lifting the vehicle.
2. Remove the lug nuts and take off the wheel.
3. Remove the brake caliper by unscrewing the caliper bolts (usually 14mm or 17mm).
  - Tools Required: Socket set, torque wrench.
4. Suspend the caliper using a bungee cord to avoid strain on the brake line.
5. Remove the brake rotor by unscrewing any retaining screws and sliding it off.

3. Replace Wheel Bearing

Sub-steps:
1. Remove the axle nut using a socket (typically 30mm or 32mm).
2. Disconnect the hub assembly from the control arm by removing the bolts (usually 19mm or 21mm).
3. Pull the hub assembly off the spindle to access the wheel bearing.
4. Use a bearing puller to remove the old wheel bearing from the hub assembly.
5. Clean the hub assembly and install the new wheel bearing, ensuring it is pressed in evenly.

4. Reassemble Components

Sub-steps:
1. Reattach the hub assembly to the spindle and torque the bolts to the manufacturer’s specifications (typically around 85-95 lb-ft).
2. Reinstall the axle nut and torque it to the specified value (usually around 150 lb-ft).
3. Reinstall the brake rotor and caliper, ensuring all bolts are tightened to specifications.
4. Reinstall the wheel and hand-tighten the lug nuts before lowering the vehicle.

5. Final Checks

Sub-steps:
1. Lower the vehicle and torque the lug nuts to the specified value (usually 76 lb-ft).
2. Reconnect the negative battery terminal.
3. Test drive the vehicle to confirm the noise has been eliminated.
