Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is on a level surface.
Disconnect the negative battery terminal to prevent electrical shock.

2. Check Fluid Level

Locate the power steering fluid reservoir.
Remove the cap and check the fluid level against the markings.
If low, add the manufacturer-recommended power steering fluid.

3. Inspect and Replace Hoses

Inspect power steering hoses for cracks or leaks.
If damaged, use a socket set to disconnect the faulty hoses.
Replace with new hoses, ensuring proper torque specifications (typically 16-20 ft-lbs for hose fittings).

4. Replace Power Steering Pump (if needed)

Remove the drive belt using a belt tensioner tool.
Disconnect the power steering pump from the reservoir and remove the pump bolts.
Install the new pump and reconnect the hoses, ensuring all connections are secure.

5. Bleed the Power Steering System

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

6. Reconnect Battery

Reconnect the negative battery terminal.
Ensure all tools are removed from the engine bay.
