Thanks so far guys.
Tried it a few weeks ago, jacked up both sides.
Found little to no play, about the same on both front wheels.
Rotated each side by hand, i couldn't really pick up on any differences, if anything, only very slightly different on the suspected right side, but my judgement may have been biased.
I found an aftermarket wheel bearing for the front for $138 (Australia, with free shipping). Heard it could be anywhere between a 1-4 hour job to change. Need to be certain before i go through with it.
The noise is only heard at 70 km/h and above. At about 100 km/h it's not as bad. But at 70-80 km/h, it's the worst, which is the average speed of my regular commute.
