Any had this sound from their AU?

[Axle-F]

I'm still trying to get used to all the sounds coming from my AU, but anyone know what this could be?

When I turn the wheel it sounds like there's a rubbing sound coming out of the steering column. I can feel a very very slight resistance in the steer, that almost feels plastic rubbing on something. It happens when I turn the wheel left or right at about the 70 degrees from centre mark.

Could just be the metal contracting in the current cold weather but if anyone's had this I'd be interested to hear.
