Power Steering System

POWER STEERING SYSTEM

There is some noise in all Power Steering Systems. One of the most common is a hissing sound evident at a stand-still or at park with the engine running. Or when the steering wheel is at the end of its travel. Hiss is a high frequency noise similar to that of a water tap being closed slowly. The noise is present in all valves that have a high velocity fluid passing through an orifice. There is no relationship between this noise and steering performance.
