The power steering is all hydraulic - no vacuum. What you describe is a cold
weather phenomenon that is usually called "morning sickness." The seals in
the rack shrink and don't let the pressure develop until they warm up a bit.
It will gradually get worse, lasting longer and happening at warmer
temperatures. Rack rebuild or replacement is the real cure, I'm afraid. Not
Maybe somebody has had good results from a power steering additive that is
supposed to revive seals. At this point, it isn't likely to hurt.
