This is a pic of a small puller, readily available from Harbor Freight
being used to remove the steering arm from the idler on a BN1.
You will note that the castellated nut has been removed then installed part
way and upside down to help the forcing screw to stay centered.

The puller has to be modified slightly to fit over the arm and engage on
the pulling ears.
It is a bit of a fiddle but it works perfectly.
I see no reason why the same tool could not be used on a later steering box
or idler although opening in the puller would have to be slightly larger
for the post BN1 cars.
