Power Steering pump bubbles and whines after replacing entire steering system.

Asked by May 14, 2015 at 07:44 PM about the 2006 Chevrolet Monte Carlo LTZ

Question type: Maintenance & Repair

The reason I replaced the system is
because it leaked substantially bad,
(I had to fill it up everyday before
driving) and it kept bubbling and
whining like crazy.  I replace the rack
& pinion, both pressure and return
lines (in its entirety), the pump (a third
time), and all the seals on the lines. I
thought if I replaced everything I
would get rid of the problem but it
bubbles and whines just as much as
it did before. Please Help! And thank
you!

You may have to pull a vacuum on the system to get all of the air out.

Thank you for your response, if you don't mind asking, would you know where the vacuum is located (on pump or rack) b/c it seems like a simple unit

It is a tool for pulling vacuum on the system, it attaches where the lid goes on the pump.

Okay, I know what you mean. I'll let you know how it turns out. Thanks!

It did quiet the pump down a lot to the point you can't hear it even when turning (with the wheels off the ground. When the wheels are on the ground and I turn it and step on the gas then the whining noise returns (pretty loud). Is that normal?

Some noise is normal and it should diminish within a week or so, if it doesn't then there is something wrong inside the pump. I would recommend driving it, not just turning the wheels back and forth in one place.

Me again. Thank you for your previous responses! So 99% of the noise is gone even when turning and hardly any air gets released from the cap now. BUT, after it warms up and I drive about 10-20 miles at least and stop with with it in gear ((between 500-600 rpms (idle)) turning the wheel becomes a lot more challenging to turn, and "sloppy". Above 700-800 rpms the steering is fine. No leaks/bubbles. That probably shouldn't happen, Right?

Could be your power steering pressure switch, it is suppose to tell the ECM to idle up to compensate for power steering load.
