Needed a new ps pump for my 87 Fox. Looked high and low and no one makes new units for our cars. I never liked to use reman parts if I could avoid them, but in this instance, I had no choice. Went through 4 pumps. All whine. It works perfectly, steers fine, no leaks. Original one started leaking, but never whined. Has anyone else had similar issues? And is there maybe a better fluid or an additive that will quiet it down? The only saving grace is that at least the whine isn’t as loud as the supercharger. Lol

Type F is what's required with original pimps, but the remans may be able to run different fluid. Need to see wgats recommended by the renanufacturer.
I still run my original 1988 pump but was able to quiet it down by draining the entire system and refilling it with type F and putting a vacuum pump on the resevior while turning wheel side to side. Made a huge difference. Still whines, but nowhere what it uses to do

My pump has 150k on it, barely here it, when I changed the rack I filled it with power steering fluid and ran the engine with the return line into a bucket and kept the pump full, flushing the system, used a little more than 2 quarts. Like I said barely hear it, I only use power steering fluid.
but that's just me.

Update. Sucked about 8oz of PS fluid out of pump with wife’s turkey Baster. That didn’t go over well. Anyway, I then added 4oz of LubeGard power steering treatment and another 4oz of Lucas PS additive. Did the trick. Much quieter.
it and bought a used Ford one and that was it. Those used pumps are garbage.
