@Tynan.You need to adjust the crank bearings. I thought you'd know that!? They wear out easily. Also, could be that your cranks are the wrong colour for your frame.
I hit them with a hammer like you said and now they are excellent, but I am not sure whether they are working now or not, what do I do next ?
