Park the vehicle on a level surface and engage the parking brake.

2. Tire Inspection

Remove the wheel covers if applicable.
Inspect each tire for signs of damage or uneven wear.
Rotate or replace tires as necessary to eliminate noise caused by tire issues.

3. Drive Unit Inspection

Remove the underbody panel to access the drive unit.
Visually inspect the drive unit for any signs of oil leaks or physical damage.
Ensure all mounting bolts are torqued to the manufacturer's specifications (check service manual for specific torque values).

4. Suspension Component Inspection

Lift the vehicle using a jack and secure it with jack stands.
Check the control arms, bushings, and struts for any signs of wear or damage.
Replace any worn or damaged components as required.

5. Brake Component Check

Inspect brake pads and rotors for wear, ensuring they are not sticking.
Clean brakes if debris is present and reassemble.

6. Test Drive

After completing repairs, perform a test drive to confirm that the noise has been resolved.
Monitor the vehicle for any abnormal sounds during acceleration.
