2007 Ford Five Hundred with 73,000 miles. Is it necessary to change the power steering fluid?
Is flushing the power steering fluid important, and if so, how do you know when it needs to be flushed?
Fords are known for noisy power steering pumps, P/S fluid is just like any other oil in the car and needs service from time to time. Ford didn't put it in the required maint schedule but should be done every 30-50k miles.
