Traction-Lok Differentials

A Traction-Lok differential can be checked for proper operation without removing it from the rear axle housing.

Raise up one rear wheel and remove the wheel cover. Install the adapter for the Traction-Lok Torque Tool on the lug bolts.

Use a torque wrench with the capacity of at least 271 Nm (200 ft lbs) to rotate the axle shaft. Be sure that the transmission is in NEUTRAL, one rear wheel is on the floor and the other rear wheel is raised off the floor. Refer to the illustration for the appropriate breakaway torque required to start rotation. The initial breakaway torque may be higher than the continuous turning torque. This is normal.





The above illustration shows an 8.8-inch ring gear axle in-vehicle Traction-Lok torque check along with the minimum torque specification.





The above illustration shows a 9.75-inch ring gear axle in-vehicle Traction-Lok torque check along with the minimum torque specification.

The axle shaft must turn with even pressure throughout the check without slipping or binding. If the torque reading is less than specified, check the differential case for improper assembly.
