The video is telling you the rack is making the noise.

If you watch the other video it shows the groaning noise it can make is caused by the plastic part further up.

So based on those videos the noise this thread is about is caused by a the steering rack.

No saying that's what is wrong just saying that is what the video is demonstrating.

Thumbs down

Right... so what is the resolution for the rack making the noise?


I have googled "BMW steering knock" and it seems common acros ALL models, from the 120 all the way to the X3, and of course the X5 as well.

People with brand new cars report the very same sound.

This guy has the VERY same sound as mine.



I just removed the kick panel that's under the steering column just now and tried to give the wheel a shake while having my hands on there. There is no play in the shaft itself. Holding the shaft in place with one hand and rocking the steering wheel with the other does not seem to help the steering noise either.



I am gonna whip off the belly pan and take a look.

You are going to need two people to find this problem. One will need to be in the car reproducing the noise while you hunt from under the car.

Was thinking just now (dangerous)... are the x5's having this issue primarily vehicles with servotronic?

Whistle

Mine doesnít have servotronic. Itís the plain ol rack & pinion directly connects to the steering.

Anyway.

I have fixed my issue. The problem was in the rack itself. I adjusted the preload nut on the rack by 1/8 a turn, this made the knocking go away completely but I found the steering was too tight and didnít center properly. So I backed it off, but the knocking came back. After adjusting it 6 times or so I managed to get it to a place where it centres properly and isnít tight but has minimal knocking. Below is a video of what it sounds like. Itís a million times better than what it was before.



Itís not perfect but it appears no car is?? I tried this same steering jiggle manoeuvre on 4 different cars with hydraulic steering and they all make the same noise.

Thanks for all the input guys. I hope this assists someone in the future.

I have done two rack doctor racks and love them. Silent, smooth and work flawless. Not cheap but its the best fix if you decide to do something to the rack.

I love rack and pinion steering. But I have also had a failure from one once that makes me scared of them when they get badly worn and take no chances. I had a car once that the rack broke and it caused the passenger wheel to come loose from the rack itself internally. So the passenger wheel turned as it pleased. Drove fine down the road amazingly but things got interesting in parking lots

Weird, I thought all 4.8's were servotronic. I looked it up on Real OEM and they only show a servotronic. No biggie though.

Funny, I didn't think about adjusting that big bolt on the rack as that is what I had to do on my Mom's Infiniti FX35 to fix loose steering. Thanks for updating. Will have to file that away in the E53 knowledge base.
