Solution

1. Preparation

Tools Required: Socket set, wrench set, power steering fluid
Park the vehicle on a level surface and turn off the engine.
Disconnect the negative battery terminal to ensure safety.

2. Inspect Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check the fluid level against the markings on the reservoir.
If low, add the appropriate type of power steering fluid as specified in the owner's manual.

3. Check for Leaks

Visually inspect power steering hoses and connections for any signs of leaks.
Use a clean cloth to wipe the area around the hoses and reservoir to identify any fresh fluid.

4. Inspect Power Steering Pump

Remove the pump belt if accessible (may require loosening tensioner).
Check for unusual noises when the pump is turned by hand.
If the pump is damaged or noisy, proceed to remove it.

5. Replace Power Steering Pump (if necessary)

Tools Required: Wrench set, torque wrench, new power steering pump, new O-rings/gaskets
Remove the pump by disconnecting the high-pressure and return lines (use a drain pan to catch fluid).
Remove the mounting bolts and carefully take out the pump.
Install the new pump, ensuring all O-rings and gaskets are in place.
Reconnect the high-pressure and return lines securely.
Reinstall the pump belt and adjust the tension as per specifications.

6. Bleed the Power Steering System

Refill the power steering fluid reservoir.
Start the engine and turn the steering wheel from lock to lock several times.
Check the fluid level and top off as necessary to remove any air bubbles.
