So my truck steering column has been whistling for a long time now. When stopped at a light or stop sign - there was a very audible whistle coming from the PS system. If you turned the wheel slightly - it'd shut up.
So after dealing with that for way too long - I ordered a new GM pump - and PS lines.
I tore the truck apart - and got the new parts swapped in.
The swap took 2 nights after work - but I finally finished up.
I put in new PS fluid - turned the wheels side to side and I'm good to go.
I still need to flush out the system - but that can wait for another day.
I did have to rent the PS pulley remover/installer tool from Autozone for this swap - but otherwise it wasn't too terrible.
