Solution

1. Preparation

Tools Required: Wrench set, funnel, OBD-II scanner, flashlight, floor jack, jack stands.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the negative battery terminal for safety.

2. Check and Replace Power Steering Fluid

Locate the power steering fluid reservoir.
Using a funnel, draw out the old fluid with a turkey baster or siphon and replace it with fresh power steering fluid recommended by Toyota (typically ATF or specific PS fluid).
Recheck fluid levels after replacement.

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

Tools Required: Socket set, torque wrench.
Remove the serpentine belt by loosening the tensioner.
Disconnect the power steering pump from the reservoir and remove any attached hoses.
Replace the pump with a new one, ensuring all fittings are secure and hoses are properly attached.
Reinstall the serpentine belt, ensuring proper tension.

4. Inspect Steering Rack (if necessary)

Lift the front of the vehicle using a floor jack and secure it with jack stands.
Inspect the steering rack for any signs of fluid leaks or damage.
If the rack is found to be defective, it will need to be replaced, following similar steps to disconnecting it from the steering column and tie rods.
