A constant velocity joint transfers power between two rotating shafts or mechanisms that do not always stay in a straight line. Here's an example. In a front wheel drive, the wheels have to turn to steer, and move up and down as part of the suspension. But the wheels are driven by the transaxle in the front of the car, which is fixed. The power cannot be transferred out in a "straight line" to the wheel, but must travel through something that can "bend" as the wheel turns, but does not slip. The constant velocity joint on the axle will do that.

When a constant velocity (CV) joint is going bad, you can hear an audible "clicking" noise when you turn the steering wheel. When a drive shaft u-joint is going bad, you will usually feel/hear a "clunk" when accelerating and/or coming to a stop,
It COULD be a constant velocity joint (CV joint) going bad.

CV joint is a Constant Velocity Joint in all FWD cars and most 4WD cars. A cv joint makes your FWD car drive and turn without losing velocity.
