Solution

1. Preparation

Gather all 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 reservoir cap and check fluid level; top off with the recommended fluid if low.
If fluid is dirty or has a burnt smell, consider flushing the system.

3. Check for Leaks

Visually inspect power steering hoses, fittings, and the pump for any signs of leakage.
Use a clean rag to wipe the hoses and pump area to notice new leaks after short use.
Replace any damaged hoses or fittings as necessary.

4. Test Power Steering Pump

Start the engine and turn the steering wheel from lock to lock while listening for the whining noise.
If the noise persists, remove the drive belt from the power steering pump.
Manually spin the pump pulley to check for roughness or resistance, indicating a failing pump.

5. Replace Power Steering Pump (if needed)

Remove the power steering pump by unbolting it from its mounting bracket.
Disconnect the fluid lines using appropriate wrenches, ensuring you have a catch pan for any residual fluid.
Install the new pump, tightening bolts to manufacturer specifications.
Reattach fluid lines and refill the power steering fluid reservoir.
