Solution

1. Preparation

Gather tools for inspection and repair.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Disconnect the battery before working on any electrical components.

2. Inspect Power Steering Fluid

Remove the power steering fluid reservoir cap.
Check the fluid level; if low, top off with the manufacturer’s recommended fluid.
Inspect the fluid for contamination; replace if necessary.

Visually inspect hoses and connections for leaks.
Use a rag to clean any residue for a clearer view.
If leaks are found, replace the damaged hoses or connections.

4. Test Power Steering Pump

Start the engine and turn the steering wheel from lock to lock.
Listen for any unusual noises from the pump.
If the pump is noisy or failing, remove and replace it:
- Disconnect the fluid lines from the pump.
- Unbolt the pump from its mounting bracket.
- Install the new pump, ensuring it's securely fastened and the lines are reconnected properly.

5. Inspect Steering Rack and Joints

Lift the vehicle using a jack and secure it with jack stands.
Inspect the steering rack for any signs of damage or wear.
Check the tie rods and steering joints for play or damage; replace as necessary.

6. Reassemble and Test

Reinstall any components removed during the inspection.
Refill the power steering fluid reservoir if it was drained.
Reconnect the battery and start the engine.
Test drive the vehicle to ensure the whirring noise has been resolved.
