Apply anti-corrosion oil onto threads and seat of the pinion nut and adjust the pinion nut tightening torque and pinion bearing preload torque (P'1 ).
Pinion nut tightening torque

: 128 - 294 N.m (13 - 30 kg-m, 94 - 216 ft-lb)

Pinion bearing preload torque (P'1 )

: 0.40 - 0.78 N.m (0.04 - 0.08 kg-m, 4 - 6 in-lb)
CAUTION:
- Discard the old pinion nut, replace with new ones.
- Adjust the lower limit of the pinion nut tightening torque first.
- If specified preload torque is exceeded, replace the collapsible spacer and tighten again. Never loosen the pinion nut for further preload torque adjustment.
- After the adjustment, rotate the companion flange back and forth 2 to 3 times to check for unusual noise, rotation malfunction, and other malfunctions.
Apply multi-purpose grease lightly and evenly onto an O-ring, and install it to the pinion sleeve.
CAUTION: Discard the old O-ring, replace with new one.
Assemble the selected pinion sleeve shim.
Install the pinion sleeve assembly, and apply anti-corrosive oil onto threads and seats on the mounting bolts. Tighten to the specified torque.
Tightening torque 25.5 - 33.3 N.m (2.6 - 3.3 kg-m, 19 - 24 ft- lb)
Check backlash, preload torque, tooth contact, and companion flange runout. Refer to PRE-INSPECTION .
The Total preload torque is as follows:

Total preload torque

With all oil seals installed: P'1 + 0.45 - 0.47 N.m (0.045 - 0.048 kg-m, 3.9 - 4.1 in-lb)

Without transfer case oil seal and gear ring oil seal

: P'1 + 0.35 - 0.37 N.m (0.035 - 0.038 kg-m, 3.1 - 3.2 in-lb)
