Power Steering Pump Replaced Still Buzzing

[influence]

Replaced the PS Pump and Bled the system.....
When the car is at idle it makes a buzzing sound and when I accelerate it gets louder, but when I turn or put any pressure turning on the Steering Wheel the buzz goes away?

Does anyone know what would cause that?

Thanks in advance

It take a new pump about 500 miles or so to break in and stop that.

A buzzing could also be from a clogged line, backing up the fluid and puttng a strain on the pump. Might want to check all the lines.

I jacked up the car this time and turned the key (did not start) and beagn turning the wheel back and forth...alot of air bubbles keep coming out. I made sure the line at the bottom of the res. was tight and the side pressure fitting as well. I also used a new teflon o ring.

I check all the lines and they look/feel tight

Does this mean I have a ton of air in the system or there is a leak somewhere?

Nearly every Ford ps pump I have had has had a buzzing noise, some worse than others.

My Capri wore out one, and the replacement was really loud. They seem to last pretty well so I gave up worrying about it.

Mine sounds like a blower. Kind of a cool sound... I do hope it will calm down, it's pretty loud.
