Solution

1. Preparation

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

2. Inspect Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check the fluid level; add fluid if low.
Inspect the fluid for contamination or discoloration. If dirty, proceed to replace the fluid.

3. Check for Leaks

Visually inspect all power steering hoses and connections for signs of fluid leakage.
If leaks are found, replace the affected hoses or connections as needed.

4. Replace Power Steering Fluid (if necessary)

Using a suction tool, remove the old power steering fluid from the reservoir.
Refill with the manufacturer-recommended power steering fluid type.
Bleed the power steering system by turning the steering wheel from lock to lock several times with the engine running.

5. Inspect and Replace Serpentine Belt (if necessary)

Check the condition and tension of the serpentine belt.
If worn or slipping, remove the old belt by releasing the tensioner.
Install a new serpentine belt according to the manufacturer's routing diagram.

6. Test Power Steering Pump

If the whining persists, the power steering pump may be faulty.
Remove the pump from its mount and inspect for signs of wear or damage.
Replace the power steering pump if necessary, ensuring to properly bleed the system after installation.
