Hydra boost/ poiwer steering

Ok, have not visited for a while, but I am available now and back to the forum. I am having a couple of issues, but first is the power steering.
My truck is making a really bad whining sound every time I turn the wheel and apply the brakes, so I took it into a diesel performance shop that specializes in diesels and so forth. They said my whole hydra boost unit was bad. It is leaking from the cap. They told me the part was around 500—600 dollars and another 500-600 for labor to fix it. Therefore, I drove it home not trying to spend that much money. I am also confused on the parts need/required to fix the hydra boost. Every time I look up hydra boost for my truck 2001 f350 7.3 I get different things. Can someone point me in the right direction regarding the parts necessary/required to replace this? I want to replace the entire power steering assembly while I am it like power steering pump, whatever is required for the hydra boost, and add a red head steering box to help with the EXTREME play I have in the steering wheel. My wife won’t touch the truck until I get the steering play fixed and worked out lol. My friend did it to his truck and absolutely loves it and it took out all of the play in his steering wheel. Sorry, if I am not up to par about this, but always willing to learn/contribute. Thank you.

did you try flushing the system first. a good synthetic atf quiets the pump down tremendously.

and are they sure your pumps bad, did the check all your steering linkage as well.
tie rods and ball joints could be shot. especially with 40 inch tires.
and you can always try adjusting the steering box first
performance shops arent always go to for maintenance items. you can probably get a real mechanics shop to fix it for cheaper. atleast the "performance shops" we have here in town.

Yes, I tried flushing it a while ago and it is still doing the same thing, however, like I mentioned it is leaking from the brake fluid add yellow spout head. I need to update my signature, because now I am on 35's lowered the truck haha. and the tie rod ends and ball joints were replaced about a year ago
