Wheels bearings that are worn make a “humming”, “whirring” or “soft rumbling” noise that comes from the corner affected.
If you have one affected, what you need to do is listen for it to find out if it is coming from the front or rear. Then, find a parking lot, make some hard right and hard left turns. While making the turns, the sound should get louder, or disappear, depending on whether the faulty bearing is under load (louder) or not (quiet).
So for example, if the humming is from the rear and gets louder during a hard right and vanishes during a hard left, then you know that it’s your rear-passenger wheel bearing.
breathes Whew. Did that make any sense?
EDIT: UNLESSSSSSSS it’s your leather-seat-lumbar-super-support-adjuster-bearing…then you’re screwed!
