What symptoms cause you to seek a replacement? Do you have metal flakes in your fluid, a leak or both?
Ha! I decided to pop back in for a few minutes. Need to get my body temperature down a bit anyway - it’s hot “out”!
Anyway, it’s fluid leakage, mostly from the bottom half of the pump. Possibly the shaft seal, too. Hard to see, there, in this car. (Subie Outback with almost 270k miles on it. Pump is original, I think.
I replaced a seal on the top connector, maybe 2 years ago, and that’s holding up ok. No metal flakes observed. Definite groaning sounds at low (winter) temperatures. Steering otherwise sounds and feels fine.
