c. Using SST to hold the flange, torque the nut.
SST 09330-00021
Torque: 108 Nm (1,100 kg-cm, 80 ft. lbs.)
24. INSTALL DIFFERENTIAL DRIVE PINION PRELOAD
a. Using a torque wrench, measure the preload of the drive pinion.
Torque:
New bearing 1.1 to 1.7 Nm (1.1 to 1.7 kg-cm, 9.6 to 14.8 inch lbs.)
Reused bearing 0.6 to 0.9 Nm (6 to 9 kg-cm, 5.2 to 7.8 inch lbs.)
^
If the preload is greater than the specification, replace the bearing spacer.
^
If the preload is less than the specification, replace the nut with 13 Nm (130 kg-cm, 9 ft. lbs.) of torque at a time until the specified preload
is reached.
Torque: 235 Nm (2,400 kg-cm, 174 ft. lbs.)
If the torque exceeds the maximum while retightening the nut, replace the bearing spacer and repeat the preload adjusting procedure.
NOTICE: Do not loosen the pinion nut to reduce the preload.
HINT: This preload is within the backlash between the drive pinion and ring gear.
25. INSPECT TOTAL PRELOAD
a. Using a torque wrench, measure the preload.
Torque:
Total preload 0.3 to 0.5 Nm (3 to 5 kg-cm, 2.6 to 4.3 inch lbs.)
26. INSPECT DIFFERENTIAL RING GEAR BACKLASH
a. Using a dial gauge, check the backlash of the ring gear.
