I flushed my power steering today and was very surprised to see that as soon as I started the engine the system spat out a quart of fluid in about 5 seconds, regardless of whether I was turning the wheel or not. I was expecting it to only spit out fluid when trying to turn the steering wheel. Is this normal? Clearly with the rate at which it was moving the fluid, the pump is working ok, so is this indicative of a steering gearbox issue? Also, after flushing the fluid it seemed that the power steering would quit more quickly. Normally it takes quite a bit of driving to get the motor hot enough for the power steering to start to fail.
