Operation Check

Tool Required:

• Traction-Lok Torque Tool T59L-4204-A

 WARNING: A VEHICLE EQUIPPED WITH A TRACTION-LOK DIFFERENTIAL WILL ALWAYS HAVE BOTH WHEELS DRIVING. IF, WHILE THE VEHICLE IS BEING SERVICED, ONLY ONE WHEEL IS RAISED OFF THE FLOOR AND THE REAR AXLE IS DRIVEN BY THE ENGINE, THE WHEEL ON THE FLOOR COULD DRIVE THE VEHICLE OFF THE STAND OR JACK. BE SURE BOTH REAR WHEELS ARE OFF THE GROUND.

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

Raise one rear wheel and remove the wheelcover. Install Traction-Lok Torque Tool T59L-4204-A on the axle shaft flange studs.

Using a torque wrench of at least 271 Nm (200 lb-ft) capacity, rotate the axle shaft. Be sure that the engine is not running, the transmission is in NEUTRAL, one rear wheel is on the floor, and the other rear wheel is raised off the floor. The breakaway torque required to start rotation should be at least 27 Nm (20 lb-ft). The initial breakaway torque may be higher than the continuous turning torque, but this is normal. 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 proper assembly.
