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.
