Default Is my power steering pump going bad?

I drive a 2006 WRX TR with approximately 123k miles on it.

About a month ago, my accessory belts began whining, so I replaced the power steering belt and a/c belt with gates belts. The power steering belt was a PAIN to get on... I had to pry it over the alternator pulley with a freaking screwdriver. I tightend the belt down so that the vertical portion of the power steering belt on the right side could be pushed in about a half inch.

A few weeks later, I noticed a whining coming from what I believe was my power steering belt. It seemed to be more noticeable when my car was cold. Shortly after I began noticing the whine, my power steering started to studder from time to time... sometimes at low speeds and more recently even on gradual turns on the highway.

I decided to replace my power steering fluid. Instead of draining it, I got a turkey baster kind of thing and suctioned it all out, refilled it, and drove it around my neighborhood a little bit. I repeated the suctioning/refilling process 3 or 4 times hoping that the fluid was the problem.

The studder did not go away.

I have never opened up the power steering system alllowing air to potentially get in... so based on what I've read, it sounds like my power steering pump may be goin gout. I called a local dealership and they said it was very rare for the pump to go bad. They also said that they thought the pump would run me around $575... ouch. I found this rebuilt pump on RockAuto -> Link that is only $151... so not as bad but also not new.

Is there any possible solution to this problem other than replacing the pump? Is it possible that I just wore the pump out from over tightening the power steering belt? Is there any reason that I might have air in the system even though I haven't done anything to get air in it?

I had same symptoms with mine a year ago.
Next time you hear that noise take a look at the p/s reservoir and look for signs of air. What condition are the hoses in? Mine were pretty hard and air was getting in past the clamps. Replacing the hoses are a lot cheaper then the pump.

Check the clamp on the suction hose going to the pump and the o ring under the suction plastic fitting. I would replace those first before the pump.

I'm dealing with a similar issue right now. For the past month or so, I've been getting the whining sound when the car is cold, and then it goes away pretty quickly. I was really hoping it was just a belt issue, so I replaced both accessory belts last night, but no dice. I guess I'll wait a couple days and see if anything changes.

Update from above^^^

After waiting a couple days I re-tightened the new belts. It continues to make the same noise after cold startup whenever the wheel is turned. I have no evidence of leakage, and it almost never shutters during turning. Sometimes at idle speed when I turn the wheel while sitting still it will shake a little, but that's it. Under normal driving conditions I have no symptoms that something is wrong. Also, the stock clamps on my PS lines have already been upgraded to hose clamps, so I really don't think air is the problem.

Does anyone have any other ideas for me to try, or should I get ready to remove/rebuild my PS pump?

I had whining and the cold/warm issue you're describing. I was losing fluid slowly. Did the rebuild (posted in the thread referenced above). Car is quiet and happy... Me too.

Rebuild or replace the pump.

I had bad juddering symptoms when turning and it turned out to be the 1 o-ring.

The o-ring pack of 50 was like $6 and with screw drivers and 15 minutes I replaced it.... judder GONE.

Look at the bearing behind the center of the pulley. Bunch of greasy crud? Maybe a slow leak. If you still have your previous used pump, rebuild that sucker.

How long does it take before it's noticeable? My wrx (04) over night developed a steering issue. I can here the pump groan if I'm stopped and I turn the wheel and at low speeds my wheels shutter. It is also significantly harder to turn the wheel. It literally started doing this over night. Possibly pump?
