Solution

1. Preparation

Gather tools and materials:
- Jack and jack stands
- Socket set
- Torque wrench
- Power steering fluid (if low)
- Lubricant or grease

2. Inspect and Refill Power Steering Fluid

Locate the power steering fluid reservoir.
Check the fluid level and condition; if low, top off with the recommended fluid.
Inspect for leaks around hoses and connections.

3. Replace Worn or Damaged Suspension Components

Remove Wheel:
- Loosen lug nuts and lift the vehicle using a jack.
- Secure with jack stands and remove the wheel.
Inspect Suspension:
- Check control arms and ball joints for wear.
- If damaged, use a socket set to remove the old components and install new ones, ensuring to torque bolts to manufacturer specifications.

4. Wheel Bearing Inspection/Replacement

Check Bearing:
- With the wheel removed, manually spin the hub; listen for grinding sounds.
Replace if Necessary:
- Remove the hub assembly if grinding is heard.
- Use a bearing puller to extract the worn bearing.
- Install a new bearing, ensuring it is properly seated, then reassemble the hub and wheel.

5. Reassemble and Test

Reinstall the wheel and torque lug nuts to specification.
Lower the vehicle and perform a test drive to ensure the noise has been resolved.
