Power Steering Pump/Gearbox Problems Due to Fluid Contamination on Ford Aerostar

Failure to change the power steering fluid can cause the fluid to become gray with metal particles. The contaminated fluid can damage the power steering pump resulting in a growling noise when the wheel is turned; the damaged pump will require replacement to eliminate the noise.. Life of the power steering gearbox and pump will be shortened if the fluid is not serviced regularly.
