AXLE AND DIFFERENTIAL: REAR DIFFERENTIAL CARRIER ASSEMBLY: REASSEMBLY - (Continued)
21. INSTALL REAR DRIVE PINION NUT
(a) Apply hypoid gear oil to the threads of the rear drive pinion nut.
(b) Install a new rear drive pinion nut to the differential drive pinion. Using SST, tighten the nut while confirming the preload.
SST : 09564-16020
without SST - Torque : 245 Nm (2500 kgf-cm, 181 ft-lb for less)
with SST - Torque : 223 Nm (2273 kgf-cm, 164 ft-lb for less)
HINT
Use a torque wrench with a fulcrum length of 500 mm (19.685 in.).
22. ADJUST DIFFERENTIAL DRIVE PINION PRELOAD
(a) Using SST and a torque wrench, inspect the preload (starting torque).
SST : 09556-16011
NOTICE:
For a more accurate measurement, rotate the bearing forward and backward before adjusting.
(b) If the preload is insufficient, use SST to tighten the drive pinion nut 5 to 10° at a time. Measure the preload and repeat the adjustment as
necessary until the preload matches the specified torque.
