Power Steering Pump - DIY

I was having some terrible noise coming from my power steering and thanks to Dave96dcm and others for helping me confirm that it was the pump.

The Stealership wanted $900 I believe to replace this new (might have been more now that I think about it.) And someone here (thanks) pointed me to a parts yard in Providence RI that had used and rebuilt parts. I got what looked like a really nice used pump for $75.

In addition to the pump, 1 quart of transmission fluid is needed to complete this DIY.

First get some help:







Then take a look at the top:






Step1 - remove all the fluid you can from resevoir:

part2: Power Steering DIY

Jack up Car, I like to use this for a jack point. Then I put a jack stand under the side where the outside jack point is - and lower the car onto the jackstand:






Remove the splash guard from under the front. You will need a Phillips screw-driver. Just turn these 180 degrees the screws donít come out, just turn them to unlock.






Remove the cap off the front of the belt tensioner and I used an Allen wrench and breaker bar at the top of the car - from the top push to right to loosen belt...reach down and pull it off pulleys.

Remove the 2 hoses going to the power steering pump, one of these required an open-end wrench larger than I had >16mm (17mm?):






Remove the power steering pulley, 3x 13mm small bolts. This is part of my Turner Motorsports underdrive pulleys so I was very careful not to damage it. Was a real problem for me because I couldn't figure out how to do this without the pulley turning...so I locked a vice grip on it...not want I would have preferred to do:






I also noticed that a duct that vents air to the alternator had been worn / damaged by the belt at some point:






The Bentley Service Manual said to remove the sway bar, so I did - but in hindsight I don't know that is nessasary. Take out the 3 bolts on Power Steering Pump to remove it.

I can't tell you how helpful your DIY instruction were for me and my 2001 325i. Had the old pump out and the new one replaced in roughly three hours, very easy thanks to you, Chronic2112. Thank you!

+1 Chronic! Replaced mine today in about 3 hours or so. Took my time, used your DIY as a basic guideline and knocked it right out.

part 3: Power Steering Pump DIY

Put the pulley back on, sway bar, belt (oh yea, before you take the belt off write on it with Chalk noting which direction is goes so that you can replace it the same way...I'm sure many people take advantage at this point to just replace it with a new one.)

Put the splash guard and everything else back together and lower the car.

I added about 1 QT of transmission fluid to the reservoir while the car was running...turn the wheel back and forth and add a bit more till it's at the 'full line'.

AND OMG it sounds so awesome now! Purs like a kitten now!


I hope this helps anyone else that needs to do it and has yet to tackle it. On a scale of 1 to 10 (10 being the most difficult DIY) I would give this about a 3.5 -didn't require a lot of crazy tools and would take someone about 1-2 hrs. total.

Tim

Thanks Hamann, I wanted to also add...

These are the 3 bolts you have to remove on the Power Steering Pump:

There are many online resources: realoem.com, bavauto.com and more.

I would suggest what someone pointed me to, look for a local auto parts yard, if you want something cheap. But expect to pay $100-$300 for a used/rebuilt one. Have to look locally for Houston.

Good luck!

btw, out of curiosity, what pressure PS is that pump. Does it say on the sticker ? Mine (later type LUK LF-20) was 110.

There was a label on the pump but I didn't really look at it too closely as the one I got came from a 1999, 328i, manual, Sedan. And I visually inspected it to make sure it was the same as my pump. Good question though...

Yeah, I was thinking there's this story that at some time BMW made a mod that "lightened" the steering, then because drivers complained of having less "feel" they made it slightly heavier again. I'm guessing at some point between your year and mine they introduced a higher pressure pump (120 - 130 PS ?), then went down to 110PS again. But I'm just guessing ? That's why I thought it would be interesting to know.

That, and consider I use underdrive pulleys that turn slower at the same RPM as the OEM pulleys...so my PS Pump is probably operating at a slightly lower pressure.

Very niceeeeee.....good DIY...and nice pics...

also if i might add...in order to get the bolts out of the power steering pulley without out using a vice grip and possibly damaging the pulley...you have to loosen the bolts before you remove the belt

Yes it's a Torx. T-20 or 25, IIRC.

Great DIY.... I have power steering fluid leaking directly from the pump elbow (Large circle in your picture). Can I tighten or replace just that part or will I need to replace the whole PSP?



If I do have to replace the whole PSP, its going to be more work for me cus of my SC

TIA,
Charlie

Beat me to it! I was going to give the same advice. Nice writeup, so how much PS fluid leaks out when you remove the hoses? Is a catchpan necessary? That was the only other thing that was missing in the writeup.
