Solution

1. Preparation

Gather tools and parts required.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Disconnect the battery if working on electrical components.

2. Inspect Power Steering System

Check the power steering fluid level using the dipstick on the reservoir.
If low, refill with the manufacturer-recommended fluid.
Check for leaks in the power steering lines and connections.

3. Examine CV Joints

Raise the front of the vehicle using a jack and secure it on jack stands.
Rotate the wheels to inspect the CV joints for any tears in the rubber boots.
If the CV joints are damaged, replace them by:
1. Removing the wheel.
2. Removing the axle nut with a socket.
3. Disconnecting the lower control arm to free the axle.
4. Replacing the damaged joint with a new one.

4. Check Wheel Bearings

With the wheel removed, grasp the hub and shake it to check for play.
If there is noticeable play or roughness when spinning the bearing:
1. Remove the brake caliper and rotor.
2. Unscrew the bearing assembly and replace it with a new bearing.
3. Reassemble the components in reverse order, ensuring proper torque specifications are followed.

5. Inspect and Replace Suspension Components

Visually inspect struts and control arms for any signs of wear or damage.
If any components are worn, replace them by:
1. Removing the affected component.
2. Installing the new part and tightening fasteners to manufacturer specifications.

6. Reassemble and Test

Reinstall the wheel and lower the vehicle.
Test drive the vehicle to ensure the grinding noise is resolved.
