Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, fluid catch pan.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the negative battery terminal to prevent any electrical shorts.

2. Inspect and Replace Power Steering Fluid

Sub-steps:
1. Remove the power steering fluid reservoir cap.
2. Check the fluid level and condition; if the fluid is dark or contaminated, it needs to be drained.
3. Use a fluid catch pan to drain the old fluid completely.
4. Refill with manufacturer-recommended power steering fluid (check the owner's manual for specifications).

3. Check and Replace Power Steering Pump

Sub-steps:
1. Visually inspect the power steering pump for any signs of wear or damage.
2. If the pump is faulty, remove the serpentine belt using a socket set and tensioner tool.
3. Unbolt the power steering pump from its mount and disconnect the hydraulic lines (using appropriate flare wrenches).
4. Install the new power steering pump, ensuring a proper seal on the hoses, and torque bolts to manufacturer specifications.
5. Reattach the serpentine belt and check its tension.

4. Inspect Steering Rack and Hoses

Sub-steps:
1. Inspect the steering rack for any leaks or damage.
2. Check all hoses for wear, kinks, or leaks; replace any damaged hoses.
3. Ensure all connections are tight and secure.

5. Reassemble and Test

Sub-steps:
1. Reconnect the negative battery terminal.
2. Start the engine and allow it to idle while checking for any leaks.
3. Turn the steering wheel fully left and right to ensure the power steering system is functioning correctly.
4. Test drive the vehicle to confirm that the whining noise has been resolved.
