Rotating Torque Check

  1. Set the parking brake, and block the rear wheels.
  2. Raise the front of the vehicle, and support it with safety stands in the proper locations (see SAFETY STANDS ).
  3. Remove the front wheels.
  4. With the ignition switch turned OFF, shift the transmission into neutral.
  5. Measure the rotating torque with a beam-type torque wrench in the direction shown. Rotate the torque wrench more than two complete turns, and take the maximum reading.

  6. Shift the transmission into 1st gear, and measure the rotating torque again.
  7. Calculate the rotating torque.

    Service Limit: 

    Measurement from step 5/Measurement from step 4 GREATER THEN EQUAL TO 2.5 

    For example: 

    7.8 N.m (0.8 kgf.m)/2.9 N.m (0.3 kgf.m)=2.67>2.5 

  8. Repeat steps 3 through 6 for the other wheel.
  9. Replace the limited slip differential assembly if the rotating torque is lower than the service limit.
