Solution

1. Preparation

Gather tools: Socket set, fluid catch pan, and wrench set.
Ensure the vehicle is parked on a level surface and the engine is off.
Allow the engine to cool if previously running.

2. Check Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check the fluid level; add the recommended fluid if low.
Inspect the fluid for contamination; if dirty, proceed to replace the fluid.

3. Inspect Power Steering System

Examine all power steering hoses for any cracks, leaks, or signs of wear.
If leaks are found, replace the affected hoses.
Check connections for tightness and security.

4. Inspect and Replace Power Steering Pump (if necessary)

Disconnect the negative battery terminal.
Remove the serpentine belt from the power steering pump pulley.
Unbolt the power steering pump from its mounting bracket.
Disconnect the fluid lines using a wrench, allowing fluid to drain into the catch pan.
Install the new power steering pump by reversing the removal steps, ensuring all connections are secure.
Torque bolts to the manufacturer's specifications (typically around 18-22 ft-lbs).

5. Refill Power Steering Fluid

Refill the power steering fluid reservoir with the recommended fluid type.
Start the engine and turn the steering wheel from lock to lock several times to bleed air out of the system.
Check fluid levels again and top off if necessary.
