I am sorry of this is a very obvious issue but I cannot seem to fit the driveshaft correctly on the car.

There is a small rigid plastic ring that seems to sit on the end of the drive shaft and locate on the face of the hub itself - the issue I am having is that where it seems to fit - is not far enough forward - so when you push the driveshaft splines all the way home and do up the nut its crushing the plastic ring and then you can hear it rubbing as the wheel spins.

I'm almost certain this is whats damaging my ABS sensors?

Having looked more closely air the hub - should the ring sit all the way into the hub which seems tough to get it through the gap or is there a trick?

Advice needed please?
