I need more TIME!

Default Best way to bleed PS pump ??

I did some searching and read a bunch... but there is rather limited info on this topic.

I Just replaced both PS pumpes on Both my subarus

I put a JDM pump in my 98 RS, and a stock Legacy PS pump in my 98 Legacy...

BOTH of them are STILL HARD TO TURN


The impreza has bubbles still in the top of the resovoir, whats the best way to get rid of all the air ???

The Legacy must have some air in it as well, because After I took the cap off and turned the wheel a few times it got better....

I have them both outside with the PS caps off, I have turned lock to lock at least 10 times in both of them...

what should I try now ???

Get the front wheels off the ground, then you can turn back and forth a lot without stressing the system.

probably ok for a while. I'd imagine it puts a lot of stress on the steering linkage

ok I tried the trick on my Impreza, and I think its back to normal...

Unfortunatly, even when I jack the Legacy's ENTIRE front end off the ground, the steering has "bumps" or tough to turn spots in the steering

I'm guessing iether my tie rod ends, or steering rack is shot ???

the tie rod ends don't click or anything though... so I'm leaning twards rack...

Lucas stop leak will smooth out minor notchyness in a steering rack. It won't stop leaks though, ironically :-) It could also just be stiff u-joints in the steering column, I had the one at the rack input jam with mud during a rallyx once and it poped the seal on the rack when I forced the wheel to turn, fun.

UPDATE:

ok am I retarded ??? I can NOT get iether one of my cars to turn correctly !

I picked up a bottle of the Lucas Powersteering goop for the Legacy, drained my reservoir and added/waited , added/waited untill it was about perfect level. I jacked up the front end and proceeded to turn the wheel (slowly) lock to lock about 5 times, then I started it up and did it again another 10 times... NO IMPROVMENT whatsoever

I also jacked up the front of my Impreza , took the cap off the PS reservoir , and did the SAME bleeding procedure,(because the top of the reservoir is a milky color) but about twice as many times... & its STILL hard to turn !!!...the car only has 45,000 miles on it, and turned PERFECTLY before I swapped the PS pump. The new PS pump has got to be almost BRAND new, because there isn't a spec of rust on it., its JDM. The only thing that is bugging me is there is a connector coming off the pump that my RS does not have stock... whats this connector for ???

What am I doing wrong ???

Ok wait a second, were you having this problem before you changed the pumps? Were the pumps leaking? Like I said before also check everythign int he steering column that might be in need of lube.

on the Impreza, no there was nothing wrong with the steering at all. it worked 100%. I just stole the pump off it to put on the legacy. and since I had an almost brand new JDM one sitting around, I put that on the Impreza.

Now I'm almost 100% sure the Legacy needs a new rack...it is pysicaly exhausting to turn the steering wheel now at least 90% of the time

I'm fighting a loosing battle here guys

actualy the Impreza one seems a bit smaller. I removed that one today, and installed the one from my GF's 95 Legacy L... I believe its the exact same pump.... No improvment

on the bright side, I can swap out a PS pump in about 10 minutes now


now the question... Used steering rack, or brand new...

Well considering they both worked fine, then you removed and installed the pumps, and now neither work, It must be something you did wrong during the reinstall.

Lots of variables going on here. I was going to say it might be seized strut bearings but it's more likely something you did installing the pump. Lines backwards maybe? Belt not tight enough?

i had this problem with my 02. it sounds like you made the same mistake i made. when you turned the wheel the first time after you replaced it were the wheels off the ground? if not you probably ruined both of your pumps...

I think I am confusing you guys due to BOTH of my cars...

The LEGACY steering started getting ROUGH to turn...
I stole my RS pump , and put it on the Legacy... no improvment (because its the rack)

THEN I upgraded my RS pump to a JDM PS pump...
And its giving me problems now...

I did NOT know you needed the front end jacked up when you first turn the wheel...
I think that might be it I must have toasted both pumps

you live, you learn ...

now I probably need 2 PS pumps and a steering rack
