(e) Using SST, turn the differential assy right and left 2or 3
times to allow the bearing settle.
SST 09564−32011
(f) Using SST and a torque wrench, measure the turning
torque of the differential case assy.
SST 09564−32011
Turning torque at 60 rpm:
New bearing
0.20−0.69 Nm (2.0−7.0 kgfcm,1.8−6.1in.lbf)
Used bearing
0.10−0.35 Nm(1.0−3.6 kgfcm, 0.9−3.1in.lbf)
HINT:
If the turning torque is not within the specified value, refer to the
table below and select a thrust washer which turning torque is
within the specified value.
