Battle-axe,

Thanks for your reply; There is a flange within the front hub that already does that ie grips between the outer bearing on the "back" and "front".... if you pull the "front" bearing out you can see the inner bearing sits free of this. The only component that sits across both inner and outer bearing is the c clip at the back.

Also, the 12mm hex nut has a "spacer" molded into it at the back that only pulls onto the inner bearing, when tightened - it is the equivalent of this that I am trying to source for the other end ie between the c clip and the back bearing.
