It depends on the kind of knocking.... I have had 2 vehicles with knocking. 1 was related to the heating system or ignition andould quit shortly after starting the car. The other vehicle which was a Toyota 4 runner was in the engine. It also depends on how loud the knocking. May not be helpful but look into it.
