grease sealant composition has a constant speed

The invention relates to a grease composition for constant velocity joints, comprising: (a) a base oil; (B) a diurea thickener based on the formula (1): (CF DRAWING IN BOPI) wherein R1 and R2 may be identical or different and represent aryl groups having 6 or 7 carbon atoms or cyclohexyl; (C) a molybdenum dialkyldithiocarbamate; (D) molybdenum disulfide; (E) at least one extreme pressure agent selected from the group consisting of zinc dithiophosphates and extreme pressure agents based on sulfur-nitrogen; and (f) an extreme pressure agent based on sulfur, phosphorus-free. The grease composition has a low coefficient of friction, decreases although the induced thrust and has good durability.
