Well, we're back to the 08 now...

So the PS pulley sheared off my 08 2.5i Outback 45 miles from home, and I was able to make it home without alternator, as i had to remove the belt.

I got a used (91K miles salvage) PS pump for $60 with pulley, as I thought it would be cheaper/easier than rebuilding the old one and I don't know if it can be done. The shaft had all the notches worn off. I'm assuming the numb nuts that replaced a motor used it for a lift point...

Anywhoo, the **** thing is making noise, a lot of noise, and I don't know if maybe I got a bad pump or what. It is hard to turn, it "gets stuck" at certain points, as in you have to use a bit more pressure to turn it if say locked going straight. NOt easy to turn the wheel, noisy, etc. I have put about 20 miles on it, done side to side turns, etc...

I have also noticed that it seems to have "overpressured" ??? the system, as fluid has leaked around the elbow on top, as well as overflowed the reservoir. I'm trying to get this car ready to possibly trade or sell...LOL...

Could I have possibly gotten a bad PS pump? I noticed I can get a reman for around $100 give or take, but thought this might have done the trick, since I havent' hear of PS pumps failing that often (other brands at least).

Rack was replaced when I boutht the car 2 years ago.

I have perused this thread which gave me a little help, but not curing any issues.

Any clues? Wanna buy it? LOL

Did you bleed the air out of it? The bleed procedure in the FSM is very specific.

Your PS issues sound an awful lot like air in it.

Fluid leaking around the pump certainly sound like it has an air leak due to the infamous O-ring going. Or maybe due to something worse.

That's what I'm thinking. I need to put it up on stands and do it properly. Might also get a new elbow and gasket, incase it's letting air in. Lastly might just get a remanufactured unit, and learn my lesson on salvage parts. Thanks!

power steering that year is super annoying, lots of issues and repeats are not uncommon.

replace the oring, make sure the suction line end clamps are tight on the hose, and get all the air out.

make sure the hose isn't so brittle that the clamp isn't really squeezing it tight and making it air proof.

i'd replace the oring every time on one of these, it's just not worth the headache for how problematic the oring, lines, and pump are on that year.

it's not overpressurizing it's just too much air and foaming up.

get all the air out of the system and see where you're at. i just turn them lock-to-lock a bunch of times and make sure the reservoir is topped off before any driving/sloshing out. they can be insanely loud as youre bleeding so we really don't know if it's air or another issue.

it woudn't be a surprise for the oring or pump to be problematic on that year.....they're that bad. i want to start converting them to 00-04 power steering they're such a mess. or i guess just go buy all OEM pumps and hoses for $500. LOL

Were 09's an issue as well or was it isolated to the 08 MY? My 09 pump is kinda noisy is why I ask.

That's what I'll be picking up today, O ring and perhaps the plastic elbow just for fun. The old pump worked well until the pully decided to come off, and in the process smoothing out the splines on the PS shaft. No amount of duct tape can fix that. LOL. Unless I can take the shaft off the new ish one and put n the old one. That's not worth a $100 reman one.

And I assume if oil can get out at the o ring, air can get in, and it's just an endless cycle until its fixed..

Thanks!!

yep, same garbage power steering. they're simple at least, and ideally toss a new OEM unit on with new hoses and orings and wash your hands of it for the life of the car. a new OEM pump price often deters that. or go used or aftermarket and figure there's a good chance you'll need to replace it again which ends up sucking time.

Now is when the cussing shall begin. I picked up a brand new OEM PS pump at the dealer today. Slapped it on tonight, and BAM...still noisy. I'm trying to think back to when the old pump was on there, as the only reason I got into this project was because the bold came out, pulley sheared off the pins, and dropped the pulley off the pump. NO noise whatsoever prior to any exchanging.

The salvage 91k mile pump made noise, and I chalked it up to salvage part. $50. I paid $325 for the OEM today, with a discount, and it makes noise as well. took it on a few drives, parking lots to go lock to lock.

WHAT ELSE IS THERE?? There are no oil leaks under the car indicating the rack is bad...Plus, there wasn't any noise until after a different pump was put on, thus it has to be a pump or something closely related. Can't be an alternator can it? LOL.

Might be on the right track in that last quote. Are you certain the noise is originating with the pump itself?

There was no noise before the pulley sheared off, yet, as I understand the issue, the noise appeared as soon as the first replacement was installed.

If the pump pulley fell away from the pump, it seems to me that there's a chance it could have caused damage elsewhere in that front area. Here's a couple of possibilities:

Is the crank pulley intact? There's two parts; an inner hub (connected to the crankshaft) and an outer ring. They are separated by a rubber insulator. It's not unknown for the rubber to deteriorate, allowing the outer ring to move both axially and radially relative to the hub. When it shifts axially (toward or away from the engine), it's no longer in line with the pulleys at the pump and alternator. This causes the belt to ride the edges of the pulleys, and that could cause noise. Also, if the outer ring moves backwards, toward the engine, it will rub on the timing belt cover -- there's been cases where it wore through plastic, and hit the timing belt!

Was the drive belt replaced? If so, with a genuine Subaru part, or aftermarket? There's a number of discussions here where aftermarket belts did not fit properly. Yes, they worked, but because their length wasn't right, the tensioner had to be adjusted differently than before. This results in a bolt on the tensioner being very close, if not touching the belt, and this results in noise as the belt rubs on the bolt. Here's one example: https://www.subaruoutback.org/threads/alternator-belt-tensioner-too-close-to-belt.40587/

Correct. No noticeable noise. The pulley must have sheared off on a 45 minute interstate drive, as I got off at the exit, it was difficult to turn. So basically, no alternator, PS. No "warning issues" so to speak as far as squealing, whining or difficulty turning.

This actually happened! This car has been through the ringer...I am third owner, second owner I guess didn't do any maintenance...anyway, I ended up putting a reman motor and trans in it...but couldn't wait for my "Subaru guy" to get to it. So a local numb nuts ordered and installed said reman motor. Runs fine, etc.

HE did put a too big a belt on, which I replaced with an OEM from the dealer, because as you said, it was hitting the bolt. He also put a too long top radiator hose on, which was hitting the fan blade, but I replaced that with OEM as well...GEEZ. (I'm keeping it G rated)

I don't know if I mentioned it, but the rack was replaced a few months after we bought it in Aug 17. It was very leaky, but I had one put in.

The Crank Pulley looks good from my perspective.

I don't have access to a lift, although I do have stands that I can use to go lock to lock in the steering. I drove the car to a parking lot last night, and did a lot of steering lock to lock, and currently, the steering is still very noisy, and 'jerky' if that makes sense. Not smooth and fluid, but kind of jerks when I turn it.

Thanks!

Yes you should properly diagnose something before scripting a title with, and writing, Power Steering pump everywhere. Get a mechanics stethoscope and check for bubbles in the overflow reservoir after it's been making noise.

Wow, what a mess....good luck tracking down the issue. I wouldn't do anything until I had more clear diagnostics.

That definitely sounds like air in the pump still.

Just to backtrack a little.... you did replace the o-ring two weeks ago? And it made no difference, even with a session of turn-to-turn bleeding? If so, was it an OEM o-ring? I ask because I used one from a o-ring kit, thinking I was a usung the right size... one with a nice, snug fit. Kept getting the same issues, similar to yours, until I tried the size smaller. Felt like it went on/in too easily, but it worked perfectly and has been trouble-free since.

I just picked one up from the dealer. I should measure it to see exactly what size it is.

I pulled an o-ring out of a kit as well and broke the first one, and used a smaller second one but I've never felt like it's right.

For what it's worth, the dealer o-ring is a viton o-ring. The one I made the mistake of using in it's place is nitrile (I think? not sure... harbor freight metric assortment kit)

Check for air in the reservoir, if so try bleed it. If that doesn’t work, from first hand experience I managed to break the seal on the suction hose and reservoir while doing a timing belt change, kept sucking air until I bought a replacement new hose.

Awww, Man! Cut a dude some slack!! ???. I was on the road for a couple days this week, so I'll go back out and mess with it today. I'm only a bit of a mechanic. Timing belts, accessory belts, oil, etc. Haven't graduated to brakes and shocks yet! LOL...Thanks for the help!!

I have time to put the old beast on stands today to play around with it. It's a nice day here, so hopefully I can work some of the bubbles out. Just a FYI...

On salvage pump, I bought a new orange o-ring.

On new OEM pump, it came with the plastic elbow already assembled with I'm assuming a new O-ring inside.

I'll play today!! Plus my brother's 06 has a complete mess of PS problems, so I can use the salvage pump on his...?
