Traction-Lok(R) Differential Operation Check
Traction-Lok(R) Differential Operation CheckA Traction-Lok(R) differential can be checked for correct operation without removing it from the rear axle housing.
WARNING: Vehicle may have multiple drive wheels. Do not use engine to power the driveline unless all drive wheels are elevated off the ground. Drive wheels in contact with ground could cause unexpected vehicle movement. Failure to follow this instruction may result in serious personal injury.
Raise only one rear wheel. Install the Differential Clutch Gauge on the wheel nuts.
Use a torque wrench with a capacity of at least 271 Nm (200 lb ft) to rotate the axle shaft. Be sure that the transmission is in NEUTRAL, and that one rear wheel is on the floor while the other rear wheel is raised off the floor. The breakaway torque required to start rotation must be at least 27 Nm (20 lb-ft). The initial breakaway torque may be higher than the continuous turning torque.
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.
