Solution

1. Preparation

Tools Required: Socket set, screwdrivers, fluid catch pan, OBD-II scanner, funnel
Safety Warnings: Disconnect the battery before starting work on electrical components.

2. Check and Refill Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check the fluid level against the dipstick.
If low, add manufacturer-recommended power steering fluid until it reaches the proper level.

3. Inspect and Replace Power Steering Pump (if necessary)

Tools Required: Socket set, torque wrench, pulley puller (if needed)
Disconnect the negative battery terminal.
Remove any components obstructing access to the power steering pump.
Disconnect the power steering lines from the pump using the appropriate wrenches, allowing any fluid to drain into a catch pan.
Unbolt the power steering pump from its mounting bracket.
Install the new pump by reversing the removal process. Ensure all bolts are tightened to the manufacturer's torque specifications.
Reconnect the power steering lines and refill the fluid.

4. Bleed the Power Steering System

Start the engine and turn the steering wheel from lock to lock several times to eliminate air from the system.
Check the fluid level again and add more fluid if necessary.
