Re: Power Steering Noise at ~2,000 RPM, Only When Warm
Thanks for the replies. I ordered a new 2015 OEM rack and will be installing it Tuesday. I already pulled the old rack and it was pretty wet, so for lack of leaks anywhere else in the system I suspect that was the source of air in the system/malfunction. I also rebuilt the pump (i can provide a list of all the o-rings you need for ps pumps for an 08+ STi if anyone is interested) and replaced the suction hose line, plastic low pressure connector to the top of the ps pump, and the o-ring and metal gasket for the low/hi pressure attachments. I will follow up once everything is installed.
