Traction-Lok Differentials

A Traction-Lok differential can be checked for proper operation without removing it from the axle housing using procedure outlined below:
1. Raise and support one rear wheel, then remove the wheel cover.
2. Install adapter for Traction-LOK differential tool No. T66L-4204-A or equivalent, then connect a torque wrench of at least a 200 foot pound capacity.
3. Rotate the axle shaft. Ensure the transmission is in Neutral, one wheel is on the floor, and the other rear wheel is raised off the floor.
4. The breakaway torque required to start rotation should be at least 40 ft. lbs. The initial breakaway torque may be higher than the continuous turning torque, this is considered normal.
5. The axle shaft should turn with even pressure throughout the check without slipping or binding. If the torque reading is less than specified, check the differential for improper assembly.
