and rear axles The front axle 1s driven by a drive shaft and
differential in the same manner as the rear axle in a conven­
tional two-wheel drive vehicle. Torque is delivered from the
engine to the transmission and transfer case. which in turn,
propels the front and rear propeller shafts When in 4-wheel
drive, the rear wheels are pushing while the front wheels are
pulhng-th,s provides four points of torque and traction for
the "go anywhere" mob1hty that makes Jeep vehicles ideally
suited for multi-purpose usage.
The Quadra-Trac · Transfer Case, standard on Wagoneers
and optional on CJ-7, Cherokee, and Truck models with auto­
matic transmission, provides the correct amount of torque to
both front and rear axles at all times for "Full-Time 4-Wheel
Drive."
The Model 20 Dual-Range Transfer case is standard on CJ,
Cherokee, and Truck models with manual transmissions.
Quadra-Trac•-Full-Time 4-Wheel Drive
Quadra-Trac is a registered trademark of Jeep Corporation
signifying Quad (4-wheel) plus Trac (traction). This system is
available only on models with automatic transmission and
ullhzes a unique controlled-slip third differential which auto-
matically transmits continuous torque to both front and rear
axles in direct proportion to their needs for maximum vehicle
control, power, and traction. It is equally at home on the road
or off the road It 1s ideally suited for 4-wheel drive operations
in normal dry road conditions or in situations with mixed dry
and slippery surface conditions In rugged off-road situations
1t constantly adJusts to the terrain, sending the right amount
of torque to the axle where it's needed. With the exception of
the Emergency Drive and the optional Low Range Reduction
Unit, the Quadra-Trac System operates automatically.
WARNING:
A//
four tires used on vehicles equipped with
Quadra- Trac MUST be of the same type and size and inflated
within the specified pressure range at all times. Unlike t,res
could cause poor performance, poor steering, unusual
noises, or premature wear of drive train components. Refer to
Tires and Wheels section.
Emergency Drive
In some emergency situations-as in the case of the vehicle
becoming high-centered or stuck due to wheel spinning-it
may be beneficial to nullify the differential action between the
front and rear axles by actuating the emergency drive control.
