The present invention provides a grease composition for use in constant velocity joints, which have improved wear resistance and strength characteristics. The fat is made by incorporating into a fat of urea (A) molybdenum dialkyl dithiocarbamate, (B) molybdenum dithiophosphate, (C) 2- (4-morpholinylthio) benzothiazole and (D) calcium sulfonate. The mixed amount of (A) + (B) is made not more than 10% by weight, and (C) and (D) not more than 3% by weight respectively. Also, a grease for use in constant velocity joints also developed by adding (E) zinc dithiophosphate to the mentioned components (A) + (B) + (C) + (D) in a mixed amount of just 3% per weight. |
