The "WD" stands for "Water Displacement" and that's what it's for. Over time WD-40 turns into a thick sludge. Try using a penetrating oil like "Liquid Wrench" and let it soak - or use some graphite based lock lubricant Once the parts are free you should disassemble it and clean it with naphtha (lighter fluid).
