Power steering pump squeal?

I have 2016 tundra sr5 with 65k on it. Since yesterday there’s been a high pitched squeal associated with engine rpm . Spraying lubricant on the pulley at the top left (when facing the front of the engine) makes it go away for a couple minutes before returning.

according to this diagram, the pulley in question is the bane pump. Per google this the power steering pump?





Power steering pump does not appear to be leaking, level in the reservoir is not low.

Is it possible to change just the pulley on the power steering pump?

thanks for your time

 

Any chance it's the belt tensioner squealing?? Since the tensioner is right next to it. I changed mine maybe 2 months ago and it's been so quiet.

 

Serpentine belt, Idler and belt tensioner were replaced last year with dayco
