Solution

1. Preparation

Tools Required: Socket set, torque wrench, jack and jack stands, mechanic's stethoscope, safety goggles, gloves.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the negative battery terminal to avoid electrical issues.

2. Raise the Vehicle

Use the jack to lift the front of the vehicle and secure it on jack stands.
Ensure the vehicle is stable before proceeding.

3. Remove Front Wheel

Using the socket set, remove the lug nuts and take off the front wheel to access the suspension components.

4. Inspect and Replace Components

Sub-steps:
- Check the control arms, ball joints, and strut assemblies for wear.
- If any components are worn or damaged, replace them:
  1. Control Arm Replacement:
    - Remove the bolts securing the control arm.
    - Install the new control arm and torque to manufacturer specifications.
  2. Ball Joint Replacement:
    - If the ball joint is faulty, separate it from the control arm using a ball joint separator.
    - Install the new ball joint and secure it properly.
  3. Strut Replacement:
    - Remove the strut assembly by detaching the upper and lower bolts.
    - Replace it with a new strut and torque all bolts to specifications.

5. Reassemble and Lower the Vehicle

Reattach the front wheel and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and torque the lug nuts to the specified value.

6. Final Inspection and Testing

Reconnect the negative battery terminal.
Perform a test drive to ensure the noise has been resolved.
