Wheels driving while in neutral!?!

    Please someone tell me its normal, which I doubt very much! Anyway as I said, the wheels are driving while in neutral. I have the front of the car up and started it up and away the wheels went! You can imagine my surprise. I've had a new cv joint put onto one side and I've just replaced a cv boot on the other side. I can stop the drive by hand, its slow enough to catch, so I could stop the wheel, but it just started up again. Any ideas why/how this could have happened, or is it normal!?

    Sounds normal enough to me. They are not actually being driven. As you said you can stop them with your hand.

    Yeah I thought(and hoped) that. What's causing the drive then?

    It's just 'drag' between the various internals and the relatively heavy oil in the gearbox.
    Think of it as a practical demonstration of the inefficiencies and inertia that some of your engine power goes towards overcoming before it gets far enough to do useful work: turning the wheels.
