Solution

1. Preparation

Tools Required: Jack and jack stands, wheel chocks, OBD-II scanner, flashlight, mechanic's gloves.
Ensure the vehicle is on a flat surface and secure it with wheel chocks.
Disconnect the battery if working on electrical components.

2. Check Power Steering Fluid

Locate the power steering reservoir.
Remove the cap and check the fluid level; add the appropriate type of fluid (check owner’s manual) if low.
Inspect fluid for contamination (dark, gritty texture).

3. Inspect Steering Components

Raise the front of the vehicle and secure it with jack stands.
Visually inspect the steering rack for leaks and damage.
Check tie rods for play; replace if worn or damaged.

4. Check Wheel Bearings

Spin each front wheel by hand; listen for grinding or roughness.
If noise is present, remove the wheel and inspect the wheel bearing.
Replace if the bearing is faulty.

5. Examine Suspension Components

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

6. Reassemble and Test

Reinstall any removed components.
Lower the vehicle and reconnect the battery.
Test drive the vehicle to confirm the grinding noise is resolved.
