Abstract

A constant velocity joint and a boot for a constant velocity joint are disclosed. The boot generally includes a first channel and a second channel. The first channel is in fluid communication with a joint chamber of the constant velocity joint. The first channel is also in communication with the second channel and generally allows airflow therethrough while resisting clogs from lubricant. Additionally, the second channel generally allows airflow therethrough to the atmosphere while resisting passage of foreign contaminants therethrough.
