Solution

1. Preparation

Gather tools and parts.
Safely elevate the vehicle using a jack and secure it on jack stands.
Ensure the wheels are chocked to prevent rolling.

2. Inspect Suspension Components

Sub-steps:
- Remove the front wheels using a lug wrench.
- Visually inspect the control arms and bushings for cracks or excessive wear.
- Check the ball joints for any signs of play by attempting to move them with your hands.

3. Examine CV Joints

Sub-steps:
- Remove the axle nuts using a socket wrench.
- Inspect the CV boots for tears or leaks.
- Check the CV joints for excessive play or noise by rotating them manually.

4. Inspect Steering Rack

Sub-steps:
- Locate the steering rack and check for any loose connections or damaged components.
- Tighten any loose bolts to the manufacturer’s torque specifications (typically around 25-30 Nm for steering components, but verify with manufacturer specs).

5. Reassemble and Test

Sub-steps:
- Reinstall all components in reverse order of removal.
- Reattach the front wheels and torque the lug nuts to the recommended specification (typically around 120 Nm).
- Lower the vehicle and perform another test drive to check for any remaining noises.
