Solution

1. Preparation

Tools Required:
- Jack and jack stands
- Socket set
- Torque wrench
- Screwdrivers
- Fluid pump (for power steering fluid)
Ensure the vehicle is on a level surface and the engine is off. Disconnect the battery to prevent accidental electrical issues.

2. Inspect Power Steering System

Check the power steering fluid reservoir. If low, top off with manufacturer-recommended power steering fluid.
If fluid is contaminated, drain and replace the fluid.
- Sub-steps:
  - Locate the drain plug on the power steering reservoir.
  - Remove the drain plug and allow the fluid to drain completely.
  - Reinstall the drain plug and fill with new fluid.

3. Examine CV Joints

Raise the front of the vehicle using a jack and secure with jack stands.
Inspect the CV joints for any tears in the boots or signs of grease leakage.
If damaged, replace the CV joints following these sub-steps:
- Remove the wheel and brake assembly.
- Disconnect the lower control arm to access the CV joint.
- Remove the CV joint from the transmission and replace it with a new unit.
- Reassemble the components in reverse order, ensuring proper torque specifications.

4. Check Steering Rack and Suspension Components

Visually inspect the steering rack and pinion for leaks or damage.
Check for play in the steering system by moving the steering wheel back and forth while observing the rack.
Inspect suspension components:
- Check for worn bushings or struts.
- Replace any damaged components as necessary, following the manufacturer’s torque specifications during reassembly.

5. Reassemble and Test

Reinstall any removed components and ensure all fasteners are torqued to specifications.
Reconnect the battery and start the vehicle.
Perform a test drive to confirm the grinding noise has been resolved.
