Solution

1. Preparation

Gather tools and parts required for the repair.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Replace Power Steering Fluid

Locate the power steering reservoir and remove the cap.
Check fluid level; if low, add the appropriate type of power steering fluid (consult the owner’s manual for specifications).
If the fluid is dirty or contaminated, drain and replace it with fresh fluid.

3. Inspect and Replace CV Joints (if necessary)

Jack up the front of the car and secure it on jack stands.
Remove the front wheels using a socket set.
Inspect the CV joints and boots for tears or grease leaks. If damaged:
- Remove the axle nut using a breaker bar.
- Disconnect the lower control arm from the steering knuckle to free the CV joint.
- Replace with a new CV axle if necessary, ensuring the new part is properly lubricated.

4. Inspect and Replace Wheel Bearings (if necessary)

Check for any play in the wheel bearings by gripping the wheel at 12 and 6 o'clock and rocking it.
If play is detected, remove the brake caliper and rotor.
Use a socket set to remove the wheel hub assembly. Replace the wheel bearing using a press if needed.

5. Reassemble and Test

Reinstall all components in reverse order of removal.
Tighten all bolts to the manufacturer’s torque specifications.
Reconnect the battery and test drive the vehicle to ensure the grinding noise is resolved.
