A grease composition for constant velocity joints comprises: a) a base oil; b) a lithium-containing tickener selected from the group consisting of lithium soap and lithium complex soap; c) an organic molybdenum compound selected from the group consisting of molybdenum dithiophosphates and molybdenum dithiocarbamates; d) a zinc dithiophosphate; and optionally (e) a metal salt selected from the group consisting of metal salts of oxidized waxes, metal salts of petroleum sulfonates and metal salts of alkyl aromatic sulfonates. The grease composition for constant velocity joints exhibits a substantially improved effect of reducing friction coefficient and a substantially improved effect of preventing the occurrence of vibration.
