Drive Axles

The front drive axles for all wheel drive
equipped models use two different
types of constant-velocity (CV) joint.
The outer CV joints are a traditional
design that allows power to be
delivered from the axle to the joint
continuously through rotation.
The inner CV joints are triple roller
bearing joints. This design minimizes
the amount of vibration and noise
transmitted back through the vehicle
drivetrain, while also allowing the axle
to move in and out to compensate for
suspension travel.
To replace a CV joint or dust boot, the
drive axle must be removed from the
car.
