Steering gets stiff when weather gets over 90 degrees or hotter

I have a 2004 Mustang and when the weather gets hot my steering goes bad. I am able to turn the car but its a loud grinding sound. Any advice?

If rack seals are weak, it is usually worse when cold (morning sickness). Since The problem is when hot things are hot, I suspect the pump. I’d search for the location of the noise With a mechanic’s stethoscope or listening hose. And I’d see how the fluid looks and if it smells burned.
Now if you have Electric assisted steering, please disregard my post.

Thanks so much, I will look into it!
