What is a CV Axle and What is its Role?
The Constant Velocity (CV) axle assembly transfers rotational drive torque from the transmission transaxle differential to the wheel hub assemblies while accommodating steering and suspension travel.
Primary Component Location: Extends horizontally under the front wheel arches, connecting the transmission side gears to the wheel hubs.
