Rack Adjustment?

Hi guys,

I have some slop in my steering rack and had it checked out by a reputable BMW mechanic recently. I'm told that they can "dial out the slop by adjusting the rack". I've never heard of this before and did not think the rack was adjustable.

Can anyone provide comment on what they may be referring to? If so, is it DIY?

Thanks!
NicB.

I've heard of people doing this before with good results. I am not sure though. Here's something

Used to be able to 'dial out the slop' with the old recirculating ball steering gearboxes pretty easily but it was only a bandaid. If you have steering slop in the rack it is because the rack is wearing out and there is nothing you can do about it really, except maybe do what the guys in the video are doing which I would assume is a bandaid just like the steering box adjustment was. This is why you change out your steering fluid and keep your steering gear in good shape. If I were you I would just buy a good rebuilt unit which definitely is a DIY and declare victory. Unless the indy mechanic is offering to do it cheaply, which I doubt since it probably involves removing the rack for bench adjustment. Lots of labor there. If it were me I'd just get a new rack.

Yes, you can adjust the rack if you think you need to. That's why there is an adjustment screw present.
I did this with my e30 after swapping e36 rack.

The adjustment area located where the pinion gears meet. If I recall properly, I believe it takes 17mm wrench to do this. Usually adjustment within 1/2 turns from the original mark is enough. "Screw in" for tightness and "Screw out" to loosen it.

Don't go crazy with screwing, as the rack gears can either lock up for being overly loose, or be too flash against each other and will introduce extra stress and wear when it is too tight.

^^Thanks for the info. The mechanic said they could do it for an hour of labor.

He's attempting to match a specific amount of rotation with a specific torque level. As an example, he's trying to turn the shaft 60 degrees with 5 ft/lbs of torque.
