On-Vehicle Torque Bias Tests
On-Vehicle Torque Bias TestShift the transfer case into the 4-High position.
Place the vehicle on a level surface. Stop the engine.
Place the transmission shift lever in the Neutral position and the transfer case shift lever in the 4-High position.
Raise one front wheel off the surface. Remove the hub cap from the raised wheel.
Assemble a socket and torque wrench and position on any lug nut of the raised wheel.
Rotate the wheel using the torque wrench and note the torque required to rotate the wheel.
If the coupling is operating properly, it should require a minimum of 61 Nm (45 ft-lbs) to rotate the wheel.
If the required rotating torque is at or above the specified limit, remove the wrench, install the hub cap and lower the wheel.
If the required rotating torque is below the specified limit, remove the wrench, install the hub cap, lower the wheel and refer to the On-Bench Torque Bias Test.
