My Honda CRV left front wheel recently gives off a sound like woh - woh -woh - woh. It becomes noticeable at 35 kph and increases in repetition rate as the car goes faster. I don't feel any vibration at the steering wheel at any speed. I've jacked up that side and tried to turn that wheel to see if it's out of round, but it won't turn easily (automatic trans is in neutral). I think it's the tire but the wheel bearing is also suspect. I could change it with the spare to find out but it's very late at night and I'm too lazy to do it tomorrow before I go to work. What do you think, guys? Tire or bearing?
