So I also thought this, I heard some scratching a few months ago and felt the hub get hot so took it to the garage who looked it over and said there wasn't anything wrong. Its front right was making the noise and the turns were both turns.
The abs ring which is picked up by the abs sensor will move out of position if the bearing starts to fail, meaning no speed is passed back to the abs/traction control computer. The pickup then thinks there must be a fault as the other 3 wheels are all doing the same speed.
Moment we start
That's a wiring fault or knackered sensor.
). Replaced that, but yeah that affected the sensor again. Haven’t bothered to get around to getting it sorted out yet . . .
