There is generally a center shaft underneath the drivers side opposite the transmission that connects the 2 CV axles. There are bearing in it that can go bad and cause vibration. If you replace a motor mount you must replace the whole set. This is because the others are fatigued and the new one will put more of a load on the old ones and they will fail quickly and then your new mount will fail. You should also replace the transmission mount.
