PS Problems

[SkunkyZ]

I just got a new power steering pump and threw it on. As soon as I start the car and turn the wheel the pump whines like crazy. Is it a bad pump or is there air in the lines.

I tried the bleed the system for about ten minutes and drove around for about 10 min and the whining didnt go away and the power steering seemed to get worse and started to go in and out.

Any help is appreciated.

Could be either, or both. Sometimes you get an air pocket in the rack and it takes time to work its way out. Give it a little and see if it goes away. If not it could be a bad pump

If there was an air bubble in the rack would it cause the pump to whine? And the whine only occurs when the pump is under a load like when I turn the wheel or hold the wheel all the way to the right or left. Also if i rev the motor when turning the wheel the whine gets super loud.

I already swapped my old one back in that doesnt work at all becuase I thought the new one was junk so i was gonna return it. The old one doesn't make any sounds but also doesnt have any power steering but it does flow a little because i can see some fluid get pumped into the tank every 2 seconds.

Would it be worth it to try the new pump again and see if it gets better?

They aren't too hard to swap out so trying a new one would be worth it. It very well could be a bad pump if it is still whining.
