2006 Jeep Commander 2 wheel drive. I'm getting whirling noise when accelerating at low speeds. It sounds very similar to a manual car going in reverse. You know, when they sound like a little remote control car? Anyway, I'm getting that noise going forward. It tends to go away at about 30 mph. Not sure if the road noise just drowns it out, or if it actually stops. I've read on here it could be a wheel bearing problem. Does this sound right? What else should I check?
