a. Using a torque wrench, measure the preload of the backlash between the drive pinion and ring gear.
Preload (at starting):
New bearing: 1.1 - 1.7 Nm (11 - 17 kgf-cm, 9.6 - 14.8 inch lbs.)
Reused bearing: 0.6 - 0.9 Nm (6 - 9 kgf-cm, 5.2 - 7.8 inch lbs.)
^
If the preload is greater than the specification, replace the bearing spacer.
^
If the preload is less than the specification, retorque the nut with 13 Nm (130 kgf-cm, 9 ft. lbs.) of torque at a time until the specified
preload is reached.
Torque: 235 Nm (2,400 kgf-cm, 174 ft. lbs.) or less
^
If the maximum torque is exceeded while retightening the nut, replace the bearing spacer and repeat the preload adjusting procedure. Do
not loosen the pinion nut to reduce the preload.
75. INSPECT TOTAL PRELOAD
a. Using a torque wrench, measure the preload.
Total preload (at starting): Drive pinion preload plus 0.3 - 0.5 Nm (3 - 5 kgf-cm, 2.6 - 4.3 inch lbs.)
76. INSPECT DIFFERENTIAL RING GEAR BACKLASH
77. INSPECT RUNOUT OF REAR DRIVE PINION COMPANION FLANGE SUB-ASSY REAR
78. INSTALL REAR DRIVE PINION NUT
a. Using a chisel and hammer, stake the drive pinion nut.
79. INSTALL REAR DIFFERENTIAL SIDE GEAR SHAFT SEAL OIL
a. Using SST and a hammer, install 2 new oil seals until they are flush with the carrier end surface.
SST 09550-00032, 09950-70010 (09951-07200)
b. Coat MP grease to the oil seal lip.
80. INSTALL REAR DIFFERENTIAL SIDE GEAR SHAFT DUST COVER
a. Using a steel plate and a press, install a new dust cover.
NOTICE: Be careful not to damage the dust cover.
81. INSTALL REAR DIFFERENTIAL SIDE GEAR SHAFT SUB-ASSY (W/O TORQUE SENSING LSD)
