Solution

1. Preparation

Gather tools: socket set, torque wrench, funnel, rags for cleaning, and a multimeter.
Ensure the vehicle is parked on a level surface, and the engine is off before starting.

2. Check and Refill Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check the fluid level. If low, add the appropriate type of power steering fluid (consult the owner’s manual for specifications).
Start the engine and turn the steering wheel from lock to lock several times to circulate the fluid.

3. Inspect and Replace Power Steering Pump (If Necessary)

Remove the Belt:
- Use a socket set to loosen the tension on the power steering belt and remove it.
Disconnect Power Steering Pump:
- Remove the bolts securing the power steering pump using a socket wrench.
- Disconnect the power steering lines carefully to avoid fluid spills.
Install New Power Steering Pump:
- Position the new pump and tighten the bolts to the manufacturer's torque specifications.
- Reconnect the power steering lines securely.
Reinstall the Belt:
- Place the power steering belt back onto the pulley and adjust the tension as needed.

4. Bleed the Power Steering System

With the engine running, turn the steering wheel from lock to lock to remove any trapped air.
Check the fluid level again and top off if necessary.
