Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery if working on electrical components.

2. Check Power Steering Fluid

Remove the power steering reservoir cap.
Inspect the fluid level; add the appropriate fluid if low.
If the fluid is contaminated, flush the system and replace with new fluid.

3. Inspect CV Joints

Lift the front of the vehicle using a jack and secure with jack stands.
Rotate the front wheels by hand to observe the CV joints.
If any clicking or grinding is felt, replace the damaged CV joint or axle.

4. Examine Steering Components

Inspect the tie rods by shaking them; there should be no play.
Check the steering rack for leaks or physical damage.
Replace any worn tie rods or steering rack components as necessary.

5. Inspect Suspension Components

Examine struts and shocks for leaks or damage.
Check control arms and bushings for wear or play.
Replace any defective suspension parts to ensure proper alignment and handling.

6. Reassemble and Test

Reinstall any removed components and ensure all bolts are torqued to specifications.
Lower the vehicle and reconnect the battery.
Test drive the vehicle to ensure the grinding noise is resolved.
