The vehicle is a 2002 Ford Escape, DOHC V-6.
If I put a stethoscope on the pump, the roar that I can hear from inside the car seems to be pinpointed in the pump. The reservoir is full. Of course I can see the fluid circulating inside. The steering works normally. I can feel vibration in the high pressure line So, what’s causing the noise? I think the pump is bad, but it was replaced less than 10K miles ago.
