Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to avoid electrical issues while working on the power steering system.

2. Check and Refill Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check the fluid level; if it's low, top it off with the recommended fluid type (usually ATF or specific power steering fluid).
Inspect the fluid for contamination; if dirty, consider a fluid flush.

3. Inspect and Repair Leaks

Visually inspect all power steering hoses and connections for leaks.
Replace any damaged hoses or fittings. Use a socket set to loosen and remove hose clamps as necessary.
Tighten connections if they are loose.

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

If the pump is making noise, remove the serpentine belt using a wrench to loosen the tensioner.
Unbolt the power steering pump from its mounting bracket and disconnect the fluid lines.
Install the new pump by reversing the removal steps and ensuring all connections are secure.

5. Bleed the Power Steering System

After repairs, refill the power steering fluid to the correct level.
Start the engine and turn the steering wheel from lock to lock several times to remove any air bubbles.
Check fluid level again and add more if necessary.
