Power Steering Rebuild - notes and vents

autoxcuda,
As I recall, the rebuild kits you buy at auto parts or rockauto are just "soft parts", i.e. what is called "overhaul kit" in transmissions. I advise against opening the recirculating ball tubes, though I recall the manual shows that. The balls are likely an industry standard size. Bike supplies sell loose balls, even by the jug, but it would be lucky if a size matched. My guess is the Torrington bearings would have to come from an industrial supply like McMaster-Carr or Bearings & Drives. Same for the needle bearings at the sector shaft, and you can find many rare parts on ebay.
