- Rotate or replace tires if any issues are found.
Tools Required: Tire pressure gauge, tire iron.

3. Wheel Bearing Check

Sub-steps:
- Jack up the vehicle and secure it with jack stands.
- Spin each wheel by hand; listen for noise and feel for roughness.
- If any wheel bearing feels loose or exhibits noise, replace it.
Tools Required: Jack, jack stands, socket set, torque wrench.

4. Suspension Inspection

Sub-steps:
- Visually inspect control arms, tie rods, and bushings for wear or damage.

- Replace any worn components as necessary.
Tools Required: Socket set, pry bar for leverage.

5. Brake System Evaluation

Sub-steps:
- Remove the wheel to access the brake assembly.
- Inspect pads for wear and rotors for scoring or irregularities.
- Replace brakes if they are worn down below specifications.
Tools Required: Brake caliper tool, socket set, brake cleaner.

6. Reassembly and Final Checks

Sub-steps:
- Reinstall wheels and torque lug nuts to manufacturer specifications.
- Lower the vehicle and perform a test drive to ensure the noise is resolved.
Tools Required: Torque wrench.
