The Hurricanes halted a two-game skid, scoring the game's first three goals and getting a solid effort from the struggling Ward. He won for just the fourth time in nine games.
Brandon Prust broke up Ward's shutout bid with 8:20 to play.
Henrik Lundqvist gave up the four Carolina goals on 39 shots.
It was the fourth loss in six games for the Rangers, who could not back up their 7-0 win over Toronto Wednesday.
