It sounds as if one of my front wheelbearings is away but I jacked the car up and there is no play on the wheels. Could a bearing still be away with no play on the wheel? Or could the noise be coming from my tyres?
Wheel bearings can become noisy and will be long before they develop play. The sure-fire way to identify a noisy one is to jack the car up and run it in gear, then listen next to each one with a stethoscope. One will make some noise, but the bad one will be MUCH louder.
