Loud whining ?

Maybe you guys can give me some of your input , those of you who have chased an engine whine like I am doing right now
01 Tacoma 4wd 3.4l v6

Things I have done ,
-replaced steering rack ( was leaking )
-replaced power steering pump with a new unit , reused my resevoire but cleaned the screen before reinstalling .
- emptied old fluid and put new into the system .
-New power steering belt
Clearly I thought the noise was coming from the power steering pump but needed to replace that stuff anyways . Trying to attach a video of myself hitting the gas pedal hopefully you can hear it . Kind of two noises , one rises with the rpm and the other is kind a scraping bearing noise .

Look forward to your thoughts

 

Is there any chance the high pressure line was replaced with an aftermarket at some point in the past?

 

Some reason couldn't post my video , not compatible I guess but this video is very close . I'm assuming it's a bearing

water pump or pretensioner?

 

Lines are oem

 

Belt tensioner?

 

Rules that out.

 

Okay so some of the whining was the power steering which corrected itself after a long drive since I just put the stuff in and the annoying loud noise was that idler pulley. Went around with a long screw driver listening. Swapped it out and all good , appreciate the replies

 

that's good to hear, I have the same whine and have a new pump and pulley in the top of my toolbox. Just haven't had time this week to start the project as I want to combine it with some other work at the same time.
