Power Steering noise?

[268i]

Hi all, recently I was driving at slow speeds (5km/h) and heard a noise as I was turning the wheel. When I got home i checked,(Dry steering) and have recorded the noise.
Heres a video. https://vimeo.com/146196033

I'm not sure if the noise is there at higher speeds, but by then the road noise has already masked this noise.
Anyone know what this is? P/steer pump?

Doesn't sound like the pump. Sounds like bad bushing somewhere. I'd put it up on jack stands, crawl under it, and with someone turning the wheel see if you can locate the noise.
