Solution

1. Preparation

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

2. Inspect and Replace Power Steering Fluid

Remove the power steering fluid reservoir cap.
Check the fluid level; if it is low, top it off with the manufacturer-recommended fluid type.
If the fluid is dirty or contaminated, drain and replace it:
1. Attach a siphon pump to drain old fluid.
2. Refill with new fluid and run the engine for a few minutes to circulate.

3. Check and Replace CV Joints (if necessary)

Lift the front of the vehicle and secure it on jack stands.
Inspect CV joints for torn boots or damage:
- If damaged, remove the wheel and the axle nut.
- Disconnect the CV joint from the steering knuckle and slide out the axle.
- Replace with a new CV joint and reassemble in reverse order.

4. Inspect and Replace Wheel Bearings (if necessary)

While the vehicle is lifted, grasp each wheel and check for play:
- If play is detected, remove the brake caliper and rotor.
- Remove the hub assembly and replace the wheel bearing using a press if needed.
- Reassemble and torque all components to manufacturer specifications.

5. Reassemble and Test

Reinstall all removed components, including wheels, calipers, and any covers.
Reconnect the battery terminal and lower the vehicle.
Test drive to ensure the grinding noise has ceased.
