6. Insert DT-47687  (1) into the axle shaft opening of the differential and rotate DT-47687  (1) until it engages with the differential pinion shaft (645). See Special Tools .
7. Using a torque wrench, measure the rotational torque required to slowly rotate the front differential assembly and note the readings.

   Rotational Torque Specification:  Specification should be within 0.70-1.20 N.m (6-11 lb in).

8. If the obtained measurement is within specifications, the differential shim replacement is not necessary.

   If obtained measurement is not within the listed specifications, the front differential bearing race shim must be replaced.

9. Remove DT-47687  (1) from the front differential assembly. See Special Tools .
10. Remove the torque converter housing assembly and the front differential assembly from the transmission case.
