Jeep Wrangler: FOUR–WHEEL DRIVE OPERATION / Trac-Lok Rear Axle — If Equipped
The Trac-Lok rear axle provides a constant
driving force to both rear wheels and reduces
wheel spin caused by the loss of traction at one
driving wheel. If traction differs between the two
rear wheels, the differential automatically
proportions the usable torque by providing
more torque to the wheel that has traction.
Trac-Lok is especially helpful during slippery
driving conditions. With both rear wheels on a
slippery surface, a slight application of the
accelerator will supply maximum traction.
WARNING!
On vehicles equipped with a limited-slip
differential, never run the engine with one
rear wheel off the ground. The vehicle may
drive through the rear wheel remaining on the
ground and cause you to lose control of your
vehicle.
