A grease composition for constant velocity joints comprising: (a) a base oil; (b) a diurea thickener of the formula (1):R1NH-CO-NH-C6H4-p-CH2-C6H4-p-NH-CO-NHR2wherein R1 and R2 may be the same or different and represent aryl groups having 6 or 7 carbon atoms or cyclohexyl groups; (c) a molybdenum dialkyldithiocarbamate; (d) molybdenum disulfide; (e) at least one extreme pressure agent selected from the group consisting of zinc dithiophosphates, and sulfur-nitrogen extreme pressure agents; and (f) a phosphorus-free sulfur extreme pressure agent. The grease composition has low coefficient of friction, good performance for reducing induced thrust and high durability. |
