Question about 2003 Ford Expedition
HI. To interpret what type of noise it is in this medium is quite hard, due to the fact that, I cant be there physically to hear the noise. With that said; When a power steering pump device fails or is in decline, it will make a very loud whining noise. This sound will fluctuate, depending on how high the rpm's are at any given time. It can be at low levels at idle and can be quite annoying at high idle when you are turning your steering wheel. You will here it the most when the steering wheel is being turned back and forth. This type of power steering gear damage is due to a breakdown in the internal structure and seal sector. This will cause an unstable pressure, thus, induce that ungodly sound. It is possible to have it rebuilt, but most dealerships will simply replace it.
