I have removed the steering shaft from the car but the knuckle is well worn cracked in fAct and i cant seem to find another like it think it might be the end off litlle blue unless i can find something soonI have to say this is a really weird part to go and I've never heard of it going. Any ph2 electric power steering column will fit. You won't be able to remove the bottom half until you've undone the pinch bolt on the steering rack.
A picture will help! Just replace the column. It's a £50 part and pretty easy to fit.
