Correct me if I'm wrong, but if you go over any bumps do you hear a slight knocking/clunking noise?
That's another way to tell the ball joints are on the way out, they are stupidly common and other members have had this issue with hardly any miles on the car.
I'm guessing you're still under warranty with that mileage, yes? You should have the arms checked over at least and if it is them they should be replaced FOC.
But it sounds like you are having a similar problem to me, and the day the car was booked in for them to look at it the squeeking stopped! So they couldn't diagnose the fault. I'm unsure of the make up of the column but my guess is that its a seal/o-ring that is causing it.
