Solution

1. Preparation

Gather tools: jack, jack stands, socket set, torque wrench, and OBD-II scanner.
Ensure the vehicle is on a flat surface and the ignition is off.

2. Inspect and Replace Steering Components

Inspect Power Steering Fluid:
- Check the fluid reservoir for proper levels. If low, top off with manufacturer-recommended fluid.
Examine Steering Rack and Tie Rods:
- Remove the front wheels using a socket set.
- Inspect the steering rack and tie rods for any signs of wear or damage.
- If damaged, replace the affected components. Torque specifications for tie rods are typically around 45-50 lb-ft.

3. Check and Replace Wheel Bearings

Remove Front Wheel Assembly:
- With the vehicle lifted, remove the wheel and brake caliper.
Inspect Wheel Bearings:
- Check for any play or roughness in the bearings.
- If faulty, replace the wheel bearings following manufacturer specifications.

4. Inspect Suspension Components

Examine Control Arms and Bushings:
- Look for cracks or excessive wear on control arms and bushings.
- Replace any worn components, ensuring proper torque settings when reinstalling (usually around 70-80 lb-ft for control arm bolts).

5. Reassemble and Test

Reattach the wheel and brake caliper.
Lower the vehicle and perform a test drive to ensure the grinding noise is resolved.
