Rubinm- glad to hear it's working for you. I have a Question tho. What steps did u go about to bleed out the air this final time? Did u put the wheels in the air and turn them with the car off? Or with the car on? Also did u turn the actual rim/wheel or did u do it thru the steering wheel? Did u go lock to lock or just right before lock? And how many times did turn them untill u were satisfied with it? I know i'm asking alot of questions but I'm just so fed up with this issue cuz it's been sitting in my driveway on stands for like 3days now and I still can't figure it out. Also thanks MasterKwan for helping out the noobs like us.

When this happened to me, I was one step away from buying a new pump. I just happened to be talking to my Subaru parts buddy asking about getting an immobilizer key programmed for my swap. He took me over to the master tech, who had just that day been working on Subaru's for 25 years. I just mentioned in passing my PS problem and he said, they replace those clamps any time they so much as bump the tank to pump hose because they've had too many comebacks and impossible to bleed cars.

With antilock brakes,it can take some time for the system to work the air free.

sorry - my bad. I've been chasing brake problems and I'm thinking one-track. Forgive the sidetrack

I figured you hadn't read the whole thing. Pressure bleeding will get the air out of the ABS unit. It's how I did it when my system was dry.

Unfortunately i may have spoken too soon and my problem is not totally fixed. it seems to be about 75% better, however at times i still lose powersteerting and i get a very choppy , shudder in my wheel when trying to turn around in parking lots and such.

seems like there is still some air in the system. whats wierd is the groaning was present on start up, then i drove the car about 20 miles or so and its gone. however despite the groan going away i still have choppy steering and some shudder. - air left in the rack perhaps?

I'd give it a week and see what happens. It's possible the pump got damaged from running dry. It's hard to say at this point.

I dont know if it was suggested or not and I'd rather not sort through the previous posts but did you try turning the wheel side to side while the engine was running? My car was down for close to a year and the ps was whining and shaking like crazy after I put everything back together. I put the car up on jackstands and with the engine running, turned the wheel slowly from side to side a few times until it cleared itself. The pump will keep pushing fluid through and, eventually, it will bleed itself of trapped air.

Well gents, my suspicions were correct. today i replaced the two remaining spring clamps on the system - the one on the pump, and the clamp on the upper portion of the hose before the reservoir that clamps the upper section of the Powersteering return line.

my powersteering is 100% fixed now

cant tell you how relieved i am that its not a problem with the pump!

im still in awe that the stock spring clamps could let air in, but not leak fluid. im also kinda miffed as to why they started leaking air after i took the banjo off the pump.. musta let air in, and once it was in there the suction of the pump trying to pull fluid through the system continually pulled more air in.

anyway. to those who doubted Kwan's recommendation to replace hose clamps that you never touched or never expected to be the culprit- change your clamps!!! i wonder now how many folks complaining to their dealers of powersteering problems paid for new pumps when all they needed was 4 dollars in hose clamps.. well, glad i didnt have to!

thanks again MasterKwan for a really sound bit of advice

Kwan and Subie909- & rubinm,

I'm having the same issue with my car '05 STi since last week we replace the clutch. I have follow this tread but still, shaking & whining ps. Did replace 2 clamps, one at the pump & the other one on that same hose at the resevoir. I'm planning to change the ps fluid what fluid do you guys recommend me to use?

rubinm I'm glad for you that your ps isue is over.

Thanks in advance

Dan

Dan- i really suggest you replace ALL of the clamps.. there are 3 more on the system.. just follow the lines to find them.

as for fluid, the car calls for Dextron III automatic transmission fluid (ATF) - i know its wierd, you're thinking "its a powersteering system! it needs powersteering fluid!" WRONG. do not put PS fluid in your system. read the cap of the reservoir, or your owners manual for reference

Redline synthetic is awesome stuff, Mobil 1 synthetic would be my next choice..

i replaced the 2 clamps, and it didnt fully fix my problem. i had to replace all of them to completely fix the situation

Rubinm-glad to hear ur all fixed now.
i replaced 3 clamps on mine(2 at bottom of resivior, and top suction side on pump) and after trying to bleed the air out all weekend i finally gave up and decided to take it to my local dealer. when i took it in i explained to the service writer what the issue was and like 45 min later he called me and said that they are going to order all new powersteering hoses because the old ones are too hard and wont hold a good seal. i guess with all the heat under the hood those hoses get cooked to the point where they feel like hard plastic.

Thanks to everyone that put there 2 cents in.

rubinm - How did you bleed your ps system wheels on the ground left -- to -- right -- to left --- right or with the front of car lifted?

Im glad I saw this thread,I put a steering rack in my old car (05 sti) and have been trying to get rid of this bad shuddering problem.I took out the reservoir and cleaned it,I completely flushed the power steering system and Im still getting a slight shudder.I have heard from other techs that it could take up to a week to get rid of all the air.I will be checking those hose clamps when I get the car back for its tune.I have been wrenching on Toyota's and Lexus since the mid 80's and never had this problem.The sc400 from Lexus must be bled with the engine off and you have to turn it lock to lock at least 25 times maybe even 30.If you dont you wont have any power steering.

subscribed. My power steering has never been the same since I did the P&L rotated kit. I followed the directions to the T -- but apparently if you leave them dry for a couple of days. ( I did the install over a holiday break ) they can act up. It works,.. but it's noisy and a little rough.

Its surprising how much difference a few clamps make on the overall system. personally i was quite skeptical. It is interesting how the spring clamps are strong enough not to leak fluid but weak enough to allow air to enter the system upon suction.

the system will bleed itself eventually and rid itself of air... thats what its designed to do, thats why there is no convenient "bleed screw" on our power steering systems.

if you are experiencing problems or troubleshooting a powersteering problem I recommend replacing every clamp on the system with good screw down type hose clamps. like i said earlier, i was incredibly skeptical and i was thinking my bleeding procedure was what was at fault... After finally saying "ah what the heck, if im going to replace 2 clamps, i might as replace all of them" my powersteering was finally fixed and free of air in the system. After replacing them all i did was drive for a couple of days and the system bled itself.

Look at the PS tank and trace the line from the tank to the pump. Your finger will touch 2 clamps. Those are the 2 clamps to replace.

You can also replace the other two for the return line. Just follow the other hose, not leading to the pump, from the reservoir. I have yet to do this, but need to. Any best method for draining the PS fluid, other than the syphon-fill, syphon-fill, method? Just detach any one of the lines connecting to the rack?

Nice.. I just started developing this problem and I didn't touch anything. The car groans and is heavy when cold then is fine when hot. I noticed this after a very long and hot track day. Time to change clamps and fluid at the same time I guess.

MasterKwan's advice worked for me, too! I replaced my radiator, which required me to move the reservoir-to-pump hose a few times.

I tried the bleed technique, but the noise didn't fade and my wheel just kept getting heavier. I also noticed that the fluid was backfilling into the reservoir and the surface was really foamy.

I found this thread after much searching, went out and purchased 4 worm clamps for $2.50, applied them to the inlet and outlet hoses, spun my wheel a couple of times and did the happy dance.

Thanks, MasterKwan! Your insistence saved me more money than Geico!
