Its possible, but a bad wheel bearing starts out with a pretty subtle
noise
on these until/unless its really bad (i.e. about to seize).
My daughter still has the '97 that was originally mine. It is developing
a
bad bearing (a souvenir from her smacking the right front into a curb one
drunken night) The noise is so subtle, none of the professionals notice it
unless it is pointed out to them. She hears it only because she had the
car
for several years and she know what it used to sound like.
Hard to find the offending bearing in the shop also, as the bearing has to
be under load before it will make any noise.
Other things to look at would be a rotor with excessive runout which could
be pu****ng the pads too far back in causing a vibration, or (less likely),
sticking caliper pins. Were you able to check that the calipers move
freely?
