I said on my starting thread the p/s had the wrong fluid in it. This was not factual. I will talk to the subaru mechanic monday exactly what he put in. He gave me a partial filled bottle of it but I can't find it. I put in the new o-ring and took it for a short test drive. Half of the old o-ring was actually flattened out. The steering seemed better than before. The same pressure when turning and no slipping. I did however have a knocking noise when turning at slow speed. Also with the engine running in park when I turn the wheel to the right I hear a squeaking noise right at the steering column area. Does something in this area need to be lubed? I have a re-built rack and pinion I have driven with for about a year. Around 9k miles. I'm going to have my mechanic here this noise and drive it asap. Any thoughts or suggestions welcome and thanks for the feedback.
