I am talented with a mallet

Lunch time project it is. I shall report back

It'll probably only need a light tap. There is one tooth on the reluctor ring that is taller than all the others so that one pushes the sensor out to give the correct air gap. At one of the Summer Camps we had a Marty's workshop, one of the guys had the ABS light on when we drove to the hotel. Nanocom said it was one of the front sensors so put the steering on full lock, got underneath and tapped it with the end of a wheelbrace, ABS then working perfectly.
