Default Power steering pump issues!

What's up guys, so my 04 Wrx wagon (110k) is having sone issues with cold horrific screetch in the power steering pump and even when warmed up sometimes the wheel has issues after about 3/4s of a turn with hesitation and jerkyness. Fluilds were all drained and replenished at 90k and the level is still good.
Do I need to check the filter? New pump? Let me know cause i don't want to go drop a **** load of money on a pump!!!!! Thanks a lot , Logan

Are you sure that the belt is good and tight enough? (just checking...)

If you've haven't replaced your pump yet, that is likely the problem. Look behind it on your block with a flashlight for the fluid pooling up. The internal o rings are probably going. You can pull and fix the pump for about $3 in o rings and your time. I bought the newer pump design on ebay for $425 and installed it. Doesn't have the o rings to fail like the original pump. I then realized how cheap and easy to fix the old one was. Fixed it and sold it in the classifieds.

There is a good thread on iwsti.com on how to pull and fix the pump.

Here is the thread:
http://www.iwsti.com/forums/how-inst...sassembly.html

One of the pages lists the o ring sizes. You need 3 and they are metric. If you can source them locally, great, if not, there's always McMaster.

I've never done the filter, but if you plan on doing this, just flush the system with fresh fluid and you should be fine. Also, get some new worm drive clamps for the rubber hoses. The spring types will start to leak over time.

I was able to get mine as a salvage part through a local Advanced. $130 shipped and about an hour to hook up and flush.

I completely rebuilt my 2004 Steering Pump. Even started a thread about it. O-ring sizes and everything.

This thread is money^^^^, however he went way deeper than needed. Here is what you will need:
2mm dia x 12mm ID for Suction Hose
2mm dia x 14mm ID for the small one (Internal pump)
2mm dia x 65mm ID for the larger one (Internal pump)
This is info I posted on the iwsti thread.

Plus new worm clamps and preferably a new suction hose from then res. and feed hose from the rack.

This is all dependent on your issue being the pump. Good luck.

I need to be spoon fed.... as Scotty says.

Do these o rings sizes work with an 02 wrx usdm pump?

No, that year uses a different pump. I think the pump in question was in the 04-05 years.

I had the same problem with my 04 wrx and it persisted for weeks. I changed the fluid, checked for leaks, checked for wear and tightness of the belt and everything looked fine. But there was still hesitation of the wheel at start up, and this awful screech came from under my hood making my car sound like a hooptie. The last thing I did was further tighten my belt and Wallah the screech and hesitation was gone. I thought my belt was tight enough too but I was mistaken.
