OEM fix for knocking steering rack
Has anyone seen this? A few members posted about this on our Facebook X3 group. Supposedly BMW came up with a fix for the bushing that wears out in the steering rack. Looks like this fix is for models that have the tightening socket with three holes in it (LCI models). I wonder if this will work on the pre-LCI models.

If you have play in the left inner tie rod area of the rack, this kit will fix it.

I went to Sebring a few weeks ago and have had this knocking sound since. Track day probably did not treat the bushing kindly.
Do you have a link to buy?

This fix is for the bushing that's on the left side of the rack. Are you talking about that?

If you follow the BMW manual, it's pretty involved since it requires $200 worth of specialized installation tools with some electronic measuring equipment to adjust the play. I think people are just installing without following the BMW procedure. steering rack knock fix 32106891974 replacment instructions.pdf |

If you don't want to use the special measuring tools, fine, but I don't recommend adjusting it by counting turns, at least make small adjustments until the play is removed then stop. |

1)Lift front wheels off the ground. 2)Grab drivers side tire at 3 & 9 o'clock 3)Push/Pull tire with high force and feel/hear knock 4)Turn adjuster clockwise in small increments 1/16 turn at a time. 5)Repeat 2-4 until knock is gone. 6)Turn steering wheel left to right lock to lock and check for binding. If binding exists, back off adjustment a hair until binding is gone. |

Well you could, but it would be better to replace the entire thrust bearing

I've cited this kit as a potential solution in thread https://x3.xbimmers.com/forums/showthread.php?t=1662030
My reply there has links to videos and install instructions. One special tool that is used to set clearances was discovered buy an independent shop I worked with to cost $1500. If it were $200 I would have purchased it and done the repair myself. I wonder which price is right. X3 is at dealer as I type this. I had to point them to the solution. Have my fingers crossed that it actually works! They are covering the cost since I had them work on the same issue once before when the rig was still in factory warranty. They deserve kudos for that and for working with a smartypants customer like me, and I'll see if it's appropriate to give their name here, and if the dealer wants that. BTW my rig has the DHP (dynamic handling package) and I think that includes variable ratio steering. It's certainly fewer turns lock to lock than the loaner G01 I have at the moment. I wonder if this issue is specific to that steering rack? Oh, and if the dealer hadn't been so accommodating I was otherwise at the point of doing what pungo suggests in a reply above. I might have done one more step: After it seemed just right I'd back off the adjustment a hair just to make sure there is no binding that I couldn't feel. If you look at the training video, the link to which is embedded in the install instructions to which there is a link in my reply cited here, you can see that some clearance is prescribed. Edit 5 Nov - the part was replaced and things are much better. Steers better, no knocking in regular driving. There is still a bit of a knock when jigging the steering wheel with the engine off. Is this OK? I dunno. When I get home I'm near gravel roads with washboard - I'll see if it still knocks there. Many thanks to BMW Northwest in Fife, WA, for their willingness to listen to my analysis, to research the issue, and to pay for the special tools needed to do the fix. Edit 18 Nov: Fix is good, no knocking noise on rough gravel roads. The residual knocking when jigging the steering wheel with engine off only occurs after the car has been driven a bit. I'm guessing the tolerances are affected by temperature. The BMW repair instructions do not address that. I guess it's good enough! Last edited by Oilverland; 11-18-2019 at 08:08 PM.. |

I thought I had this knocking but my sway bar end links were loose! I recommend all with this issue check them and tighten them. A 15 minute job that may just save you a headache.

I know Im bringing up an old thread. But my 2011 X3 has been wandering while driving. The shop took a look and initially thought it was the left side inner tie rod, but then upon closer inspection it looks like its from the rack. I would much rather pay them to install this kit as opposed to trying to pay for a new rack. Mine has play and a lot of what is mentioned, but I havent noticed any clunking or knocking noise coming from it.
