Solution

1. Preparation

Gather tools: jack, jack stands, socket set, torque wrench, fluid catch pan, and a multimeter if needed.
Ensure the vehicle is parked on a level surface and the engine is off.

2. Check Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check the fluid level; if low, top off with the manufacturer's recommended fluid.
Inspect the fluid for contamination; if dirty, perform a fluid flush.

3. Inspect Steering Components

Lift the front of the vehicle using a jack and secure it with jack stands.
Visually inspect the steering rack, tie rods, and ball joints for any signs of wear, cracks, or damage.
Wiggle the tie rods and ball joints to check for excessive play.

4. Replace Worn Components

If any components are found to be faulty (e.g., tie rod ends or ball joints), proceed to replace them:
1. Remove the wheel to access the steering components.
2. Use a socket set to remove nuts and bolts securing the faulty parts.
3. Install new components, ensuring they are torqued to manufacturer specifications.

5. Reassemble and Test

Reinstall the wheel and lower the vehicle.
Start the engine and turn the steering wheel to test for the grinding noise.
Monitor for any leaks around the power steering system.
