Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and set the parking brake.
Disconnect the negative battery terminal.

2. Check and Replenish Power Steering Fluid

Locate the power steering fluid reservoir.
Inspect the fluid level; if low, clean the reservoir cap and add the appropriate power steering fluid until it reaches the "full" mark.
If the fluid is dark or contaminated, proceed to flush the system.

3. Inspect and Replace Hoses

Visually inspect all power steering hoses for cracks or leaks.
If damaged, use a wrench to disconnect the faulty hose at both ends.
Replace with a new hose, securing with clamps and tightening to manufacturer's specifications (typically 12-15 ft-lbs).

4. Replace Power Steering Pump (if necessary)

Remove the serpentine belt by loosening the tensioner.
Disconnect the power steering pump from its mounting points using a socket set.
Disconnect the fluid lines from the pump, catching any residual fluid in a container.
Install the new pump by reversing the removal steps, ensuring all connections are tight.

5. Bleed the Power Steering System

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