I'm glad to hear that. I have to start at the tires, and work back. Who? Recommended ATF? The noise is important, in its sound and location.
A whine or growl is either pump, or the lines touching the body or frame.
A sucking air sound is an o ring or air leak.
Air in system shows up as fluid loss and sight of it in pump.
Knocking/scrubbing could be the rack ends hitting something or incorrect tire type or size.
NO vibration or rubbing in steering wheel, no sticking or difficulty turning, means it is probably pump.
I have never used ATF, ever. But they cannot get the same parts suppliers now. The heat softens seals, and tightens the punp clearances. So if the pump is whining cold, it may be a little of both.
Not the belt, tell owner its cheapest to try a pump, for now and then the rack(if bad) will just require replacement anyway because of its mileage.
It's made to be quiet and steer with adequate assist until warranty is over only. It should put 3500PSI out of pressure side of pump, and with tie rods disconnected, the wheels and tires should not bind. On flat rate we put a long extension or stethascope on the pump, if it whined alone with no movement from steering, it went, with a new res. Also.
With the rack to follow soon. Sorry. No one fooled with steering problems. Use ear plugs for now and wait till there is a windfall of cash, replace the vehicle.
Talking 3,000 dollar repair and a 500.00 gauge from Miller tolls to check pump output. I am grouchy cold also. Its hard on line. With noises. OK h broke. I don't think your going to loose your assist in an instant. No way. I guess their putting ATF in them but that was and is a no no.
You can feel, see, and hear the difference. Once, I tried to get away with just the pump because atf was used. I kept adding and adding fluid, looked down, and there were two balloons on the rack boots, about to explode, so thats what ATF did to the whole system. It was a 1999. What you hear, and what you get are two different things.
