Play at steering wheel

Hi Peeps,
The F'lander passed the MoT today ! Hoorah ! Advisory for play in the steering wheel. Haroo !
Checked the tightness and torque of the securing nut but there's still abit of play.Doesn't seem to be a steering column bush,any ideas ?
cheers,Rob.
Ps did a search but couldn't find ought.

top bush is usual suspect, or do you think loose in the splines?

Couldn't see a bush on the exploded diagram in the manual,but will give stealership parts counter a ring !

Not track rod ends??
