Rear wheel bearings

[Geraint Lloyd]

Bernie,

Must be something else then.

I have had quite a few bits apart recently so the abs issue could be
anything, although the ABS AUF light only started coming on since it snowed
here in Montreal and one has been "taking advantage" of the Quattro system

I am changing the dud bearing on Monday, all being well, so in the unlikely
event that it cures the ABS issue, then I guess that you, maybe perhaps,
might just owe me a pint!

Geraint

Our ABS is not a traction control system. It is a braking system,  
active only when braking. You speculate that there is compliance in  
the wheel bearing allowing significant changes in ABS sensor gap. I  
disagree. Even a very noisy wheel bearing will allow very little  
axial deflection of the axle.
