Hard steering
Checked the belt it's fine
Check the power steering fluid it's good
Looked for leaks and found none.
No odd noises.
When the front tires are off the ground the wheels can be turned easily either with the steering wheel or by grabbing one of the front wheels and turning them by hand.
I have no codes
I have search the forum to see what I could learn but found nothing that help me, not that I read every post.
So is it the power steering pump or the steering rack?
When I park the car yesterday everything was fine.

Also since you mention that the steering can be 'manually' turned without resistance your PS system appears to be mechanically functional. I have swapped fluid ( R&R) on higher mileage vehicles with positive results . GM synthetic PS fluid(s) are 12345866 for the smaller can and 12345867 for the larger can. I have also used Red Line's full synthetic PS fluid in other models applications for similiar symptoms with satisfactory results as well.
I track the car so I pull the power steering fluid out of the reservoir and refill it pretty regularly. I use the Valvoline synthetic power steering fluid.
