摘要： A grease-retention assembly for a drive shaft assembly with a tubular shaft connected to a joint includes an outer race and a cap for grease retention and venting arranged in an inside diameter section of the outer race. The cap includes an outer annular rim with an annular indentation. The outer race includes a radial abutment shoulder extending radially inward and defining an axial end position of the rim of the cap, and a radial annular rib extending from the inside diameter section. The rib partially fills the annular indentation of the rim when the cap is in the axial end position. The cap further includes a central portion with a hollow air cavity extending across the cap between two radially extending walls, an axial hole through one of the two radially extending walls, and a radial annular groove communicating with the air cavity.
