Constant-velocity joints (aka homokinetic or CV joints) allow a drive shaft to transmit power through a variable angle, at constant rotational speed, without an appreciable increase in friction or play. They are mainly used in front wheel drive vehicles, and many modern rear wheel drive cars with independent rear suspension typically use CV joints at the ends of the rear xle halfshafts and increasingly use them on the propshafts (drive shafts).

Make it your ambition to lead a quiet life,                                                             

to mind your own business & to work with your hands.
