Solution

1. Preparation

Gather tools: socket set, torque wrench, jack stands, multimeter (if needed).
Ensure the vehicle is on a flat surface and the parking brake is engaged.
Disconnect the negative battery terminal for safety.

2. Inspect and Replace Tires (if needed)

Remove the wheel covers (if applicable) using a flathead screwdriver.
Loosen lug nuts with a socket wrench, then lift the vehicle using a jack.
Remove the wheel and inspect for damage, uneven wear, or foreign objects caught in the tread.
Replace the tire(s) if damaged or excessively worn. Reinstall the wheel, tightening lug nuts to manufacturer specifications.

3. Check and Secure Underbody Panels

Inspect all underbody panels for loose fasteners or damage.
Tighten any loose bolts or screws, ensuring panels are secured.
Replace any damaged panels with OEM parts as necessary.

4. Inspect and Replace Brake Components

Remove the wheel to access the brake components.
Check brake pads for wear; replace if less than 3mm thick.
Inspect brake rotors for warping or damage; replace if necessary.
Reassemble the wheel and torque lug nuts to manufacturer specifications.

5. Test Drive and Monitor

Reconnect the negative battery terminal.
Test drive the vehicle to evaluate if the noise persists.
If noise continues, further inspection of suspension components may be necessary.
