A constant velocity joint for a drive system comprises: an outer joint member having a plurality of inwardly facing outer ball grooves, the outer ball grooves consisting of a first group of grooves and a second group of grooves with composite or non-linear groove pattern; an inner joint member disposed inside the outer joint member and having a plurality of outwardly facing inner ball grooves consisting of a first group of grooves and a second group of grooves with composite or non-linear groove pattern, each inner ball groove of the inner joint member being coupled with a corresponding outer ball groove of the outer joint member generally in crossed pair; and a cage having circumferentially displaced cage windows to accommodate a plurality of balls therein. The groove patterns of the ball grooves can be a combination of skewed grooves and non linear grooves, a combination of non linear of linear grooves and non linear grooves.
