Power steering pump noise

[4X4 Pinto]

I just bought a 90 Bronco II w/ 74K orig. It runs great but has a annoying whine sound which increases in pitch with the RPMs. I suspect it is the power steering pump. Fluid in it is up where it shoud be but smells burnt. Should I replace it with new power steering fluid ? What is the best way to drain all the old stuff out? My 93 F250 truck has the same noise. Hate it but I've heard worse on other older Fords.

I know very good team for the regeneration of steering gears used in BMW vehicles. They are very qualified specialists with many years of experience. https://www.steeringlpsr.com/ This team did for me a lot good jobs. !

These pumps take Type F or Dex/Merc transmission fluid. Not power steering fluid.

Someone correct me if I'm wrong, but I heard you could add friction modifier, the same stuff you add in with gear oil for limited slips, that's suppose to help quiet the pump.
