It could be your differential. Does the whine diminish when you take your
foot off the gas? Does it diminish while you are cruising on the freeway?
Is it more of a howl than a whine? Does the pitch change with vehicle
speed, rather than engine speed? Does it seem to come from the rear of the
car? If yes to all of these, I would suspect the differential, specifically
the ring gear and pinion.
