Solution

1. Preparation

Ensure the vehicle is on a flat surface and secure it with wheel chocks.
Gather necessary tools and parts.
Disconnect the battery if working on electrical components.

2. Check Power Steering System

Sub-steps:
- Remove the power steering fluid reservoir cap.
- Inspect the fluid level; if low, fill it with the recommended power steering fluid.
- Check the fluid for contaminants or burnt smell; replace if necessary.

3. Inspect CV Joints

Sub-steps:
- Lift the front of the vehicle using a jack and secure it on jack stands.
- Remove the wheel on the side where the noise is present.
- Inspect the CV joints and boots for any cracks or tears; replace any damaged parts.
- If the CV joint is worn out, replace the entire axle assembly.

4. Check Wheel Bearings

Sub-steps:
- While the wheel is off, grasp the wheel at the 12 and 6 o'clock positions and shake it; any play indicates a bad wheel bearing.
- Remove the hub assembly if the bearing is bad and replace it with a new one, ensuring proper torque specifications when reinstalling.

5. Examine Suspension Components

Sub-steps:
- Inspect control arms, bushings, and struts for any signs of damage or wear.
- Replace any worn bushings or damaged components as needed.
