Abstract
A grease composition for a tripod type constant velocity joint, which includes a base oil, a urea compound as a thickening agent, and not more than 10% by weight of at least one of (A) a molybdenum dialkyldithiocarbamate and (B) a molybdenum dialkyldithiophosphate or diaryldithiophosphate, in which the base oil has a kinematic viscosity of from 3.0 to 7.5 mm.sup.2 /sec at 100.degree. C. The grease composition applied to a tripod type constant velocity joint reduces the induced thrust force and thereby suppresses vibration, such as a shudder of a car body upon starting off and acceleration.
