Solution

1. Preparation

Tools Required: Socket set, funnel, fluid catch pan, OBD-II scanner.
Safety Warnings: Disconnect the battery before working on electrical systems.

2. Fluid Level Check and Refill

Locate the power steering fluid reservoir.
Remove the cap and check the fluid level.
If low, use a funnel to add the recommended power steering fluid (consult the owner’s manual for specifications).
Replace the cap securely.

3. Leak Repair

Inspect the hoses and connections for any signs of wear or damage.
If leaks are found, replace the damaged hoses or fittings.
Tighten loose connections and re-test for leaks after repairs.

4. Purging Air from the System

With the engine running, turn the steering wheel fully to the left and then fully to the right several times to circulate the fluid.
Monitor the fluid level and add more if necessary to avoid running dry.
Continue this process until the whining noise diminishes.

5. Power Steering Pump Replacement (if needed)

Disconnect the battery.
Remove the belt from the power steering pump using a socket wrench.
Disconnect the power steering lines from the pump using an appropriate wrench.
Unbolt the power steering pump from its mounting bracket and remove it.
Install the new power steering pump by reversing the removal steps, ensuring all connections are tight.
Refill the power steering fluid and purge the system as described above.
