Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to ensure safety.

2. Inspect and Refill Power Steering Fluid

Locate the power steering reservoir.
Remove the cap and check the fluid level.
If low, use the appropriate type of power steering fluid as specified in the owner's manual to refill.
Reattach the cap securely.

3. Check CV Joints

Safely lift the vehicle using a jack and secure with jack stands.
Remove the front wheels for better access.
Inspect the CV joints for torn boots or grease leakage. If damaged, proceed to replace them.
To replace, remove the axle nut using a socket set, then detach the CV joint from the hub.

4. Inspect Wheel Bearings

With the wheel removed, grasp the rotor and check for excessive play by moving it in and out.
If play is present, remove the brake caliper and rotor to access the wheel bearing.
Replace the wheel bearing if it shows signs of wear or grinding.

5. Check Suspension Components

Visually inspect the struts, control arms, and bushings for signs of wear or damage.
If any components are worn, replace them as needed.
Reassemble any components that were removed during inspection.

6. Reassemble and Test

Reinstall the wheels and torque the lug nuts to the manufacturer's specifications.
Reconnect the battery terminal.
Lower the vehicle and perform a test drive to confirm the grinding noise has ceased.
