    Hey all. Seem to be having a rumbling noise and vibration with the f430 when turning at low speeds. Anyone know what this could be. Maybe I’m just being paranoid but it’s not a smooth turn when going slow.

    Jack it up and see if the wheels turn ok , ie no rumble in the bearings.
    Then grab the tyre at 3 and 9 O clock and see if any movement/ knocking- this will let you feel wear in track rod ends.
    Take the wheel off and rock the disc and see if movement in the ball joints- top and bottom.
    After that clock the discs for run out

    So it was low on gearbox transmission fluid apparently. They flushed it and filled it. Seems like that cranky noise/rumble is fine now

    Next question is why was it low? That fluid had to go somewhere...
