Default Re: New PS Pump Whining! Please help!

I went through the GM bleeding procedure this morning.

Engine off and wheels jacked up turn the steering wheel left and right 40 times.

Check the fluid level and start the engine.

Turn the wheel left and right a couple of times and check the fluid level.

After doing this procedure I still have a whining noise from the pump. I am going to give it a day or so to see if any air bubbles come out.

As for the original whining noise I pulled off the serpentine belt and checked all of the pulleys. The idler pulley feels just like a new one, nice and tight with no gritty feeling. The water pump did not have any play in it and the AC compressor was tight. I'm not sure where this noise is coming from!
