Hissing noise

I think it's my power steering pump. Either the pump itself or the pulley. i had a leak from my steering rack and replaced it a while back and ever since that leak it has been making this noise. haven't noticed any change in steering. link to the video I have of it is here. Any input from yall would be awesome! Thanks

sounds like belt and the idler pulleys

 

Looks like I'm ganna try the old jug and screwdriver method

 

if you take off the belt you can twist those pulleys and see if they are turning smoothly

 

the more I listen to the vid the more I think its associated with the power steering , maybe check the PS level and change out the old ATF in there would be a good start

 

Trying to chase down a hiss I’ve noticed in my truck when turning the wheel lately. I’ve recently changed shocks to Bilstein 8112s, oem lower ball joint on driver side, oem inner and outer tie rods on both sides, cam bolts to taco tabs, sway bar end links to overland custom end links, energy suspension sway bar bushings, power steering fluid flush 8 times or more, Napa HD cv axles both sides… now I’ve suddenly gotten a hiss while turning that I didn’t notice before and I still have a click during Sharp turns.
im starting to feel like I should’ve left shit alone and dealt with the click noise I had while turning bc it seems like it’s one thing after another since I started replacing parts.
