Possible power steering pump bad?
My c5 is making a noise (generic sounding, I know)
It's a humming that seems to intensify when the steering wheel is turned, and changes in pitch with engine speed.
I can feel a humming (not shaky or violent) vibration through the steering wheel, most noticeably when at low speed or stopped.
I'm worried it's the power steering pump, but I was wondering if any of y'all had a better or more experienced second opinion? Cunningham estimated around 1500 over the phone to replace a power steering pump and that number is a bit scary so some clarity would be appreciated.
Thanks!

Yes, based on your description, it sounds like the PS pump.
Change the pump yourself, it's not hard.
Get one of these:

one (or two if you take the entire line off) of these:

You MUST change the O-rings in the line as they will have taken a set and will leak if you attempt to reuse them.
You will need to rent a PS pulley installer from AutoZone/O'Reilley/etc. to install the pulley on the pump.

As posted above. The parts are easily under $400 so over $1500 to replace the pump is quite steep. Heck, you can get a rebuilt AC Delco for $50 if you're willing to use rebuilt.

If you do change the pump and you buy a new pump and it doesn't have the pulley I would upgrade the pulley to a later version that is a little more rugged.
