Quadra-Drive

II System – If Equipped
The optional Quadra-Drive
威
II System features two
torque transfer couplings. The couplings include an
Electronic Limited-Slip Differential (ELSD) rear axle and
the Quadra-Trac II
威
transfer case. The optional ELSD axle
is fully automatic and requires no driver input to operate.
Under normal driving conditions, the unit functions as a
standard axle, balancing torque evenly between left and
right wheels. With a traction difference between left and
right wheels, the coupling will sense a speed difference.
As one wheel begins to spin faster than the other, torque
will automatically transfer from the wheel that has less
traction, to the wheel that has traction. While the transfer
case and axle coupling differ in design, their operation is
similar. Follow the Quadra-Trac II
威
transfer case shifting
information, preceding this section, for shifting this
system.
