I'd check to see if the bushing that provides drum ground has gotten pushed in on the rear center of the drum. If everything else was working when you changed it, the only things I can think of are the drum ground or possibly a wrong drum. The (some unnamed company) drums we sometimes have to use are notorious for letting the bushing get pushed into the drum.
