I just replaced my wheel bearings after experiencing symptoms like you
describe. Do the light swerving thing as suggested: if sound
changes/goes away under a certain load, this is more evidence of wheel
bearings. If you get grinding/crunching/sqeaking from the wheel(s),
ditto for bearings. Take this opportunity to get to know your CVJs
anyway: drop the half-shafts and disassemble and clean 'em. It'll buy
you another 15,000 mi until you'll hAve to do it again, if nothing else.
