I was thinking this was tied to the tcs someway, guessing, as in that system is now online, it's now ready for use.
I don't know how to explain this though.

I used to see a message before I got new hubs put on;
It would say tcs active on the dic, then I would hear the buzzing noise.

After the hubs, I don't see the message tcs active, I only hear the buzzing noise.

I now realize this has something to do with the speed sensors coming online, being tested, not real sure how to explain it, since I don't really know what it's actually doing.

Your lights are probably dimming because when you turn youre putting strain on the power steering pump causing it to bog the motor which in turn bogs the alternator creating less electricity supply for your car briefly. and the buzz is your power steering pump being strained.
