Wheel alignment issue ??

I have M60 (rear wheel steering same as you) and my issues are completely RANDOM it seems. As I mentioned in earlier post, I drive the same route to and from work, with different roads and speeds from 30-70mph. There is no consistency to when the steering gets “stuck”…..

My thoughts were also tracking issues. But it even feels like the wheels are all moving independently from each other sometimes….it’s such a difficult issue to describe! 😩
Hi Mac545,
I suspect a problem with car/wheel alignment. E.g. Camber:

If there a suspension issue, the camber can change by the pressure on the front wheels : when accelerating less pressure, when slowing down, more pressure.
Even more frontal wind can put more pressure on front wheels.
So every ride has different feeling, exactly what I also reported.

I'm an engineer and like to objectivate the problem, to measure things. So I bought a Newton meter, something like this:https://m.media-amazon.com/images/I/41uMPG6fYXL.jpg, but then for 20N.

My measument on the stearing (20cm) converted to NM gives me these results:
70km/u => 8 N or 1,6 Nm
90km/u => 10 N or 2,0 Nm
125 km/u => 14 N (deadpoint !!) or 2,8 Nm !!!

I also asked BMW Belgium to escalate this issue with the engineers in Germany.
