My Golf has just started gently thunking. It corresponds in frequency to the speed of the car and sounds like it is coming from the very front. It only is conspicuous when I am coasting, and goes away when I am accelerating or breaking. It is loudest at very low speeds. Turning does not make much difference It sounds much like there is something wrong with the tire, but the tires look fine (about 30k, good tread left). Or maybe something stuck in the wheelwell, but they look clear. Maybe the brakes are somehow out of allignment and rubbing? The car handles, accelerates, and breaks perfectly normally.
I had the car in for a 50,000 mile service last Monday, including a tire rotation and front end allignment. The mechanic commented that the car was in great shape; maybe it was a curse?! It started yesterday, and I blamed it on ice at first, but that explanation has worn thin.
Anyhow, any ideas what it could be.
