Hi All
I think there is flex in the whole system. Pure torsion in the cross shaft is, perhaps, the biggest and invisible distortion. Whilst a solid shaft will increase torsional rigidity is by less than you would think as torsion is resisted most in the extremities of the shaft diameter. To improve things Austin introduced the longitudinal chassis member with an additional bearing close-ish to the centre of the shaft. I understand these were available as a retro fit for dealers to instal when fitting coupled brake conversions (page 264 of The Source Book).
Cheers
