just an idea here, dunno if it itll eb of any use whatsoever, but on the old fiesta racks, theres a bit grub screw type thing which you can tighten or loosen to make the steering heavier or lighter. now these are obviously none power assisted racks, dunno if the assisted ones have a similar thing, but might be worth looking into, could be a case of a couple of turns with an allen key to tighten everything back up again....
