Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a level surface.
Disconnect the battery to avoid electrical shorts.

2. Inspect and Top Off Power Steering Fluid

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

3. Replace Power Steering Fluid (if necessary)

Use a siphon to remove old fluid from the reservoir.
Refill with new power steering fluid.
Start the engine and turn the wheel from lock to lock several times to bleed air from the system.

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

Remove the belt from the power steering pump using a socket set.
Disconnect the power steering lines from the pump; be prepared for some fluid spillage.
Unbolt the pump and remove it from the vehicle.
Install the new pump and reconnect the lines, ensuring they are tight to prevent leaks.
Reinstall the serpentine belt, ensuring proper tension.

5. Check and Adjust Steering Components

Inspect the steering linkage and rack for any play or damage.
Tighten any loose bolts and replace worn components as necessary.
If the steering column is damaged, it may need replacement.
