i replaced the steering rack on my 2001 outback this morning and after i finished i added fluid to the power steering steered left and right got power steering for about a minute or so in the driveway and when i went for a test drive the power steering vanished. came back home tryed steering left and right again the system is not pulling any more fluid out of the resivour and i have what feels like manual steering with 0 assist now. the power steering worked fine before the swap what am i doing wrong?

can delete or leave up for future reference. i got mad and floored it coming down my driveway and felt the power steering kick in for a second so when i got in the parking spot i revved the engine up to around 3500 while steering and could feel it coming and going until it finally had steady power steering and wasent fading out anymore. i had to rev the engine to get it to flow the rest throgh the rack.

Sounds like it needs a good fluid-flush.

awesome.  i would say turn it back and forth lock to lock like 20 times to help bleed it, but yeah you eventually got it all worked out. 

yup, jack up the front, work steering back and forth, lock to lock (engine running) many, many times.. keep on eye on the reservoir & keep it topped up with fluid. you have air in the system still and you need to get it worked out.
