WHAT IS A CV AXLE ?
Constant Velocity Joints (CV Joints)
  Front wheel drive cars need u-joints which not only allow up and down
  motion, but steering motion as well. the angle at which they turn
  requires a different design than the standard U-joint.

  Constant velocity, or CV joints are universal joints that are able to
  transfer torque at large angles efficiently. These joints transfer
  power very smoothly. They are comprised of four basic parts: 1. The
  outer section, which has grooves machined on its inner surface, 2.
  the bearings, which are usually in a "cage", 3. the inner ball, which
  has grooves on its outer surface for the bearings to ride in, and 4.
  a rubber boot to protect the unit from dirt and moisture.

  A common cause of CV joint failure is cracks in the CV boot. As dirt
  enters the CV joint, its parts grind themselves until a clicking
  noise is heard when turning, or until they fail completely. The boots
  should be replaced as soon as cracking is visible in their rubber
  folds.
Constant velocity joints because of their unique ability to overcome some of the design limitations of conventional Cardan style U-joints, have become a common component on many of today's drivetrains. You'll find CV joints used on many rear-wheel drive (RWD) and four-wheel drive (4WD) vehicles as well as on all front-wheel drive (FWD) vehicles.
Some type of flexible coupling is needed on all open driveshaft to accommodate the up and down motions of the suspension. What's more, some means of allowing the driveshaft to change length or to "telescope" in and out must also be provided because the distance between the ends of the shaft change as the operating angle of the shaft increases.

What causes a driveshaft to change length as it swings up and down? The geometry of the suspension. In a FWD vehicle, for example, the arc through which the front suspension travels is determined by the length of the lower control arm. Up and down motions of the suspension cause the front tires to scrub in and out slightly. Since the driveshaft (which we'll refer to as a haftshaft) is almost always a different length than the control arm, it wants to swing through a longer arc than that of the suspension. This would create an interference angle between the two that would tend to bind up the motions of the suspension. That's why the driveshaft must be able to telescope in and out because doing so enables it to follow the same arc as the suspension.
