So I have a new (to me) 2001 325i daily driver with 104K miles on it.

The power steering pump has bitten the dust. (It's making knocking noises, very heavy steering, vibrations, etc.) It's a LUK LF30.

I've read a bunch about LF20 (less boost, better feel) vs. LF30 (more boost, lighter steering). I can't really tell the condition of the existing high pressure hose. I am planning on replacing the hoses and reservoir when I replace the pump.

So here's my question - Do I go with the straight LF30 replacement, or, since I'm changing the hoses anyway, get an LF20?

Next - there are many used LF30s floating around. There are also a whole bunch of aftermarket and rebuilt replacement parts available. I wouldn't go used LF20, but again, there are a whole bunch of aftermarket and remans floating around.

Any specifically good sellers/brands? Any to stay away from? $$$ are a significant issue currently, and OEM doesn't seem to be all that great, anyway...

Thanks for your help!

Others may contradict what I say, but the overboosted steering around your car's era was solved by BMW with a new rack, not a pump with less pressure. I'd not experiment with underpowering your steering.

And I think others have had bad luck with other than LUK. I'd stick with oe here.

Replace your pump before it takes out your rack.
