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.
