Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface, and the engine is turned off.
Safety gear: gloves and safety glasses.

2. Check and Top Off Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check fluid level; if low, add the appropriate type of power steering fluid (usually ATF or specific PS fluid).
Replace the cap securely.

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

Tools Required: Socket set, wrench set, fluid catch pan.
Disconnect the negative battery terminal.
Remove any belts connected to the power steering pump.
Disconnect the power steering lines and allow fluid to drain into the catch pan.
Unbolt the power steering pump from its mounting bracket.
Install the new power steering pump by reversing the removal steps, ensuring all bolts are torqued to manufacturer specifications.
Reconnect power steering lines and belts.

4. Bleed the Power Steering System

Fill the power steering reservoir to the appropriate level.
Start the engine and turn the steering wheel from lock to lock several times to remove air bubbles.
Check fluid level again and top off if necessary.
