Jack the car up and have a feel of the wheels.
Hold the wheel at the 3 and 9 O'clock position and wiggle. If it moves from side to side then your looking at Track rod ends / Track rods (Currently nackered on my Focus, job for tommorow)
Hold it at the 12 and 6o'clock position and have a wiggle. If theres any movement then your looking at ball joints or wishbone bushes.
Grab the strut and make sure there aint any movemnent in that either.
I doubt very much the bearing would be that bad, if it was then you'd hear it too!
