Everybody go out and crank up your truck and apply the brake pretty hard and start turning the steering wheel. See if it becomes hard to turn near its furtherest left and right positions. Dealer has replaced my power steering pump and the Hydra-booster. Not fixed, new one on lot does it too.

Well OF COURSE! When the front wheels turn, they don't just pivot in one spot, they actually have to roll a bit if the truck isn't moving (the tire will travel through a short arc). With the brakes locked up, it's GONNA get hard when you get close to full lock, regardless of whether or not it has a new booster/pump. Do this enough times, and you'll need some new steering components, too!

The resistance you feel is designed into to system. Remember when power steering was first available on cars? You could have a tire in a rut and you could turn the wheel until it ran out of power or it broke something. There was no feedback, or "feel". This all changed in the '80s. With feedback, you have greater control, and a greater ability of recovering from an out of control situation. The resistance felt when not moving is the tire scrubbing on the ground. The added feature of hydroboost exaggerates the effect. Drive an older truck with similar equipment. It'll do the same.

It could be that yours has something wrong with it and we are just missing the point. The description you give sounds very normal. Cheers

Ya'll be nice. I just drive the thing. I'm no mechanic. This is what I am in here for, good advice. So nothing is wrong with my truck.
