Sounds like a wheel bearing, I replaced both mine because I had the ticking noise.
It was speed related too, I could really hear the noise if I drove close to a high kerb.
REALLY annoyed me for ages - didn't sound like a wheel bearing on any other car I owned, I even took the discs off to look for trapped stones
Also, with the car jacked up and the wheel off you still couldn't tell it was a wheel bearing, everything felt good.
Instant improvement when I replaced them.
