Best Answer

Universal joints (as used on a conventional prop shafts used in rear wheel drive cars) cause the output end off the shaft to rotate at varying speeds, while the input end rotates at a constant speed, i.e. it speeds up and slows down at it rotates.

Using a CV or 'Constant Velocity' joint eliminates this variation in speed.

The use of moveable joints in drive shafts is the allow for suspension/steering movements.
