Well that's a problem. I posted on here with some details of how I fixed it back around Feb 2015. After the fix, there is no free-play at all. I can see how that is the sort of thing that if you're holding the wheel and driving, you won't feel any vibration due to the dead zone. But with hands off, it can wobble a little.

Well looks like the guys posting here have convinced me of the risks of driving with odd tires.....gonna go get em alla swapped to same spec brand etc....I will for sure check your post but do recall the garage trying to rectify from below and it would not tighten up anymore......ok thanks again

Had all four tires changed to be the same tread brand etc and still at 65mph and over i get the steering wobble left to right not as far as 2cm maybe 0.5-1.0cm, have to check the looseness when the car is parked and off and will revert.

change your rotors i had the same problem fixed 95% of the vibration next i would do bushing or ball joints but start with the rotors

Hmmm good thinking, maybe an idea to get another alignment too? as for rotors gonna get them skimmed at some point but was not getting this steering shake at 65mph and over in recent past....

I wouldnt do alligment again trust me get rotors done

do you get vibration 0 -60 too and worse at 65?

try northsideimports.com out of new jersey great prices

My friend wish i was state side, am pretty long way out.

I don't get any wobble until i hit 60-65mph, and stepped on it a little today and it doesn't get less or worse at higher speed, when i say 'it' i mean the motion indicated by crude arrows in pic (0.5-1cm motion), and as I said cannot feel it in normal driving or steering, only if I use the 2 fingered andrewwynn driving tactic or let go altogether is when i see it wobble, but stays centered and I don't skew off to the left or right of road
Just don't want this to be the reason my tires get chewed especially as they are new.....

Got em all swapped today (so transfer case damage worries kinda gone) now reading up the posts and replies wondering if it is my U joint knuckle being loose causing my 60-65mph slight wobble in steering, any ideas on how cumbersome this is to do on our 3.0d? oldskewel posts it took him 5 odd minutes to do on his 3.0i.

When you say left right you don't mean of course that the steering wheel went from left to right do you? but you were just able to wiggle steering wheel on axis of steering column as such by 2 cm while car off and steering unlocked? darn mechanic just called him up querying the slight slack, and he said there is no way to remove this slack.....so am starting to fume a bit now

Sorry to hear you got all new tires and no improvement.

Here is that old post of mine on my fix back in the day:
https://xoutpost.com/bmw-sav-forums/...ring-play.html

The 2 cm I'm talking about is the rotational motion of the steering wheel about its normal axis, and 2cm is measured at the wheel. So for example a point on the top of the wheel moves 2 cm left to right while a point on the bottom of the wheel moves 2 cm right to left.

And before the fix, this was a true loose dead zone. I could wiggle the wheel back and forth and nothing at all going into the steering rack would move.

After the fix there is no dead zone. Of course if you bump or pull on the steering wheel there will be some motion, but it is a compliance as if from a spring, vs. a free dead zone.

So to be extra specific regarding what your mechanic is telling you, it's the difference between compliance and a dead zone. With engine off, steering unlocked, parked, etc. ... Before my fix, I could rotate the wheel to the right, let go and the wheel would stay in a certain spot; then I could rotate the wheel to the left and it would move 2 cm to the left, I could release the wheel, and it would stay there, 2cm to the left of where it started. After the fix, although I may be able to pull firmly on the wheel and make it move (spring-like compliance), when released, it returns to where it started unless the wheels actually moved. That is normal.

And the fix I'm talking about is not from below, it is from above, through the engine bay. I had one of my kids wiggling the steering wheel left to right while I was looking and feeling around the double-u-joint assembly to figure out exactly what was loose. Before doing it carefully, I thought the problem was in the steering rack.
