Rattling at low speeds

Hi,

It could be a broken motor or transmission mount from the your description of the noise or a faulty front axle C/V joint or wheel and tire but this would be something you would feel in the steering wheel as well. Note make sure the engine is performing like it should because low performing engines can also cause shakes and rattles. I'm attaching repair guides on noise and vibration and exploded views of your mounts and the Active Control Engine Mount. Let us know if this information is helpful and if you need more info.
