Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is on a level surface and the engine is off.
Disconnect the negative battery terminal for safety.

2. Inspect and Top Up Fluid

Tools Required: Funnel, clean rag
Remove the power steering fluid reservoir cap.
Inspect fluid level; it should be between the minimum and maximum marks.
If low, add manufacturer-recommended power steering fluid to the appropriate level.
Replace the cap securely.

3. Bleed Air from the System

Tools Required: None, but ensure a helper is available to assist.
With the cap off, start the engine and turn the steering wheel from lock to lock (full left to full right) several times.
This process helps to bleed air out of the system.
Check fluid level again and top off if necessary.

4. Inspect and Replace the Power Steering Pump (if necessary)

Tools Required: Socket set, wrench set, torque wrench
Remove any covers obstructing access to the power steering pump.
Disconnect the power steering lines from the pump using appropriate wrenches.
Remove the mounting bolts securing the pump to the engine.
Carefully lift the pump from its location.
Install the new pump by reversing the removal steps, ensuring all bolts are torqued to manufacturer specifications (usually around 20-25 ft-lbs for most pumps).
Reconnect the power steering lines securely.
