Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Replace Power Steering Fluid

Remove the power steering fluid reservoir cap.
Using a turkey baster or syringe, extract old fluid from the reservoir.
Refill the reservoir with manufacturer-recommended power steering fluid until the correct level is reached.
Reattach the reservoir cap securely.

3. Replace Power Steering Pump (if required)

Tools Required: Socket set, torque wrench, fluid catch pan.
Remove the drive belt by loosening the tensioner and sliding the belt off the power steering pump pulley.
Disconnect the power steering lines using appropriate wrenches; be prepared for fluid spillage.
Remove the mounting bolts securing the power steering pump to the engine.
Install the new power steering pump, tightening the bolts to the manufacturer's specified torque values.
Reconnect the power steering lines and ensure they are secure.
Reinstall the drive belt, ensuring proper routing.

4. Bleed the Power Steering System

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