Transmission & Drivetrain (A2/A3)Question 20 of 120
Constant-velocity (CV) joints are used on front-wheel-drive axles primarily because they:
a.Are cheaper than U-joints
b.Require no lubrication
c.Eliminate the need for a differential
d.Transmit power smoothly through varying steering angles
Explanation
CV joints deliver constant rotational speed while the axle operates through the wide angles created by steering and suspension travel. A torn CV boot lets grease escape and dirt enter, leading to a clicking noise during turns. Boot inspection is a routine maintenance check.
