Power steering pump bearing whine - time to live?
I hijacked another thread, so I figured I should start my own in the correct forum.
My MY04 WRX 58k miles recently started making a "whiny" noise from the front area of the engine compartment - the intensity and pitch increased with RPMs, so I knew it wasn't the turbo. I originally thought it might be an alternator bearing or a fraying timing belt judging from the area the sound was coming from, but I went on to find this out: Quote:

I think Legacy777 (Josh) re-built the PS pump on his Legacy - he posted a link in a recent thread. Or you could look for a used unit.
No need to go anywhere near the timing belt AFAIK - just slacken the tensioner on the alt and pop off the RHS accessory belt. EDIT: Josh's post http://forums.nasioc.com/forums/show...59&postcount=4 |

my ps pump has been making a whine for the last year since I bought my 02. It has 77k on itand still seems to function fine. I have noticed a gradual hesitation in steering assist and the sound has increased. Have you noticed if the whine increases on especially cold days like mine? I just bought a replacement one used for pretty cheap and hope this will fix the problem, but from my experience, if you can put up with the noise, the pump should last you a while.

It hasn't been extremely cold here yet - not really even moderately cold (ie, not even below 40degF for awhile). With that said, the noise didn't start until it began getting down into the 50's here, but I don't really notice the sound getting any less when the engine warms up - I just get used to it. If I listen it's definitely still there just as loud.
So far the noise hasn't gotten worse - and like you said, it's probably something I could live with until it starts affecting the pressure. I a rebuilt one for an 02 on eBay for around $190 (#190050464293) but I'm not sure if this is a good way to go or not. I'll probably download the service manuals from http://techinfo.subaru.com/ ($35 now .. ouch) and see how hard it is to take it apart and see how much the parts are to rebuild it. -Doug |

Doug,
Check with your local subaru dealership first to see if they even offer a rebuild kit. The service manuals may not even go into detail on the internals of the PS pump, because it's an item, most techs would just replace, not rebuild. |

Have you tried to turn the wheel with the engine off, does it require that much effort when the car is idling? What you're describing is somewhat normal, depending on how much assist you are getting at idle. |

I took my accessory belt off this morning and turned the pump by hand - I couldn't really feel like there was any grinding or anything, but it wouldn't spin freely when I pushed it (not too surprising - it is a pump).
The only other thing I noticed is that my power steering fluid looks brown, not red. At 58k miles should I be considering replacing my power steering fluid? |

It wouldn't be a bad idea. Just get a turkey baster, suck out as much fluid as you can from the resevoir and refill. Repeat this once or twice more and you should be good.

I don't mean to bring this back from the dead, but I didn't want to start a new thread. This dude's post ^^^ describes my issue exactly. It is basically impossible to turn the wheels left or right when the engine is at idle. Once you put it into gear and bring up the rev's, it'll move freely. I know it's the pump, and my buddy (Subaru mechanic) agree's, but I just wanted to feel out all of my options. I've sourced out a used WRX pump from an 02 with <60,000 miles for $50 before shipping. Should I just go this route, or is there any other options that are cheaper? Is it possible that there is something else wrong that could be causing my problems? I just want to make sure that I know what all of my options (if any) are that I have available. TIA Andrew |

I have the same problem with my 2002 after a night of flat spins in a parking lot and the fluid got down to just about nothing. No assist what so ever at idle and it makes a whine when you turn the wheel. Any thoughts? Also has a leak on one of the lines right under neath the downpipe.

Here it is:

Hey, My p/s went,... i guess because I'm only getting assist off idle and it has a leak in it somewhere. Will a p/s pump off an 04-06 sti work? It says they're interchangeable between wrx and sti but will it fit on my 04 wrx? Thanks

Bringing back the dead thread i guess...I live in the Chicagoland area and as the weather got colder a whine from the front of my engine has increased in intensity. As i do alot of parallel parking i noticed the p/s assist would sort of skip and the noise would increase during parking and turning. I am hoping all i need to do is replace the p/s fluid with ATF as suggested in other threads.
What steps should i take in diagnosing this problem and i was wondering if anyone has had this same problem. |

I'd start with the fluid and go from there. That is going to be the least expensive and easiest option.
