Here is a video of the sound. Fast forward to 1:15. Seems to be when you hear it the most.

After today's test it seems to be more of a tranny thing cause I clutched in at the noise went away.

I had a similar sound but was much worse. Started with ticks then got worse from there on. My bearing and hub needed to be replaced, i'm actually waiting for replacement parts now. After driving for a bit place your hand by the hub, if the bearings failed you should feel a huge difference is heat compared to the other hubs.
