2005 Subaru WRX STi – power steering problem

Dear Doctor: I have a 2005 Subaru WRX STi that I purchased in 2007 with 36,000 miles. It now has 82,000 miles and for the past year or so, the steering tends to cut out on me. I noticed it happens more on turns when I’m either accelerating or going over bumps. I’ve had a few instances where I couldn’t turn and had to back up and use both hands to turn the wheel. Would bad belts do this, or could it be the steering box? Rick

Dear Rick: There have been some problems with air entering the power steering system from a faulty inlet o-ring. This causes a loss in pressure, because the pump has passed the air in the pressure line. Have the technician check the inlet o-ring for wear.
