Actually it should be easier to turn at slow speed. "most" have "speed sensitive" steering. Means as you go faster, the power assist drops off. This is to make it safer at speed.

Wow,
It took how many answers for an accurate one to appear!!!!!! Yes, power steering in many, many vehicles, boats and more, ARE VARIABLE! The power steering systems in use for years now have multiple inputs for finite adjustments at given speeds and engine rpms. Some are called "Speed sensitive Steering" and other manufacturers call their steering systems other names. Steering parking lots is much more assisted than at any speed higher.

And, just because you're in a turn, on county road or, freeway or any other predicament where a turn of the steering wheel is needed, don't think you're gonna get "parking lot" assist, ain't gonna happen. The vehicles speed sensor(s) are putting in input to the BCM or, body control module as some mfgs call it, Jeep calls it the TIPM, or, Totally Integrated Power Module.

All those things do is, monitor all the driving situations, component operations and vehicle input and, them assist the driver in what they may need and or request, in given situations. Another prime example is "SCV" or, Speed Controlled Volume in many of todays (and for years actually) vehicles radios. The higher the speed the vehicle is driving, the more outside influence on the quietness of the inside of the vehicle. So, the sensors sense all this stuff and, as a result, TURN THE RADIO UP. And, as the vehicle slows down, so the radio volume decreases too. Heck, even my Honda GL 1800 Goldwing motorcycle has that.

So, yes, power steering DOES fluctuate in assisting power.

Yes, you are correct. But, now I'm confused. What does your post have to do with the OP's initial question about excessive no/slow speed steering wheel effort concerning his new F-53 chassis?

I posed as well to alert the OP that he does indeed have a problem. That the assist improving at higher RPMs is not normal. With Speed sensitive steering, you really shouldn't notice a difference in the effort it takes to turn the steering wheel. At speed. Less effort is needed to turn the front tires, so power assist is less.
