Loose Steering After Replacing Steering Rack

I had a severe leak coming from the steering rack. The shop I normally go to replaced it with a refurb ZF (7852974680). The leak is definitely gone but since they did the work my once loved stiff steering/feel is GONE. The told me that it feels fine to them but I can definitely tell a major difference. The other odd thing I have noticed (or it is just in my head now) is that the faster I go the steering seems more loose. Is this normal with replacing the SR or is it possible I got a bad refurb?

There's a chance that the refurb'd rack is from a 2001 model year E46. Those racks were over boosted. Also, there's a chance that the car needs an alignment. But, if the only thing changed was the rack the alignment wouldn't have changed. Check the part # on the refurb'd rack and report back.

By loose do you mean you turn the steering wheel an inch or so & the wheels don't react? Or do you mean over-assisted?

Over-assisted. When I am taking a corner now, I feel I can use my pinky finger to turn the wheel.

Yeah you probably have one of the overboosted racks.

So are my next steps is to get one that is not over-boosted? Is there a recommended rack to get? If I have to get a different brand, I fear they are not going to cover me to replace with a different one. Even with the refurb, and labor, this was close to 1K.

Go to rackdoctor and check the racks they sell. They've annotated the different a racks. Basically you want a rack from a non-2001 model year. You can call them and they give great advice.

I called rackdoctor (like you said, very nice guy). He thinks I was possibly given a 1999 model of the rack. But he told me to do the "turn test". Basically, he asked me to turn the wheel to the left until lock position. Then put your hand on the wheel at 12 o'clock and turn all the way to the right lock position and count the turns (full 360). If it took more than 3 turns then I more than likely got the wrong rack. When I did the test I was not quite at 3 turns. So according to his test I did not technically get the wrong rack but obviously something else is going on. I have read in other places that it could be a potential gearbox problem?

Loose Steering After Replacing Steering Rack

Gearbox problem?????? Not hardly unless the person was talking about the gears (the rack gear and pinion gear). Where did you get the rack?

Yeah I probably misread it. I called my shop and they said they got the part from their supplier WorldPac.

My rack was leaking too so I got a new one from rack doctor a couple months ago, my rack was a ZF with the "purple tag" and the one I have now has the "yellow tag", I don't know why, but the steering feels a lot more nervous, maybe it's only me, I don't know.

When I talked to Rack Doctor, he said I needed the purple tag so I am surprised you got a yellow tag from him. I think your use of the word "nervous" is another great way to put how my steering feels now as well.
