Hi Ken,
"growl" means different things to different folks as do most of the
other descriptions. You need to pinpoint things a bit further. I would
describe a whine as the noise that the transmission makes when it is in
first gear. A growl, I don't know. A gear noise will be constant for a
given condition & usually described as a whine. Does the "noise" occur
upon acceleration, steady speed, or coast, or a combination of these. A
pinion bearing noise will be at a higher frequency than an axle related
noise, as in once per driveshaft revolution. A wheel bearing noise will
be rythmic in sound, & at a lower frequency, as in once per wheel
revolution, sometimes described as a rumble. With no standard
terminology, it's hard to get on the same page. Hope I haven't confused
things more.
