1995 XLT SAS w D44 and D60 rear
My search skillsmust be dead today. When I start the truck I get the normal buzzing of the pump presuring up. Truck starts and runs fine, but the pump does not seem to stop whining ever as I drive, I can not hear it on the highway over tires ect but can at normal city sppeds so I assume that it is at highway speed. Just courious, is this the pump telling me it is about to die?
