Solution

1. Preparation

Tools Required: OBD-II scanner, jack and jack stands, torque wrench, socket set, and safety glasses.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Inspect Steering Components

Sub-steps:
- Raise the front of the vehicle using a jack and secure it with jack stands.
- Remove the front wheels to access the steering components.
- Check the steering rack for any signs of damage or leaks.
- Inspect tie rods and ball joints for play or wear.

3. Tighten Loose Components

Sub-steps:
- Use a torque wrench to tighten any loose bolts on the steering assembly to the manufacturer’s specifications.
- Replace any damaged or worn components as necessary.

4. Fluid Replacement (if applicable)

Sub-steps:
- If power steering fluid is low or contaminated, locate the fluid reservoir.
- Drain old fluid and replace it with the recommended power steering fluid.
- Bleed the system to remove any air bubbles by turning the steering wheel from lock to lock several times.

5. Reassemble and Test

Sub-steps:
- Reinstall the front wheels and lower the vehicle.
- Test drive the vehicle to ensure that the noise has been eliminated and steering feels normal.
